Ambergris

18 Oct

Ambergris, the most expensive excrement in the world.

It is a flammable, waxy substance produced in the digestive system of the sperm whale, normally looking like a strange dull grey rock.

Scientists believe that it may be produced to help hard and sharp objects to move through the digestive system, but in some cases the objects may become coated in ambergris and end up too large to pass through the intestine, in which case the whale vomits it up. This has lead to the confusion that ambergris is just whale vomit, when in fact it can be expelled in the whales fecal matter as well.

Ambergris has most often been found washed up along beaches, but there are cases where it has been found bobbing along in the ocean. It is most commonly used in perfumes as it has a very distinct smell, but historical records show it was also used by the Egyptians in tombs as incense and some other cultures even used it to flavour food. Its smell is often described as a marine, fecal odor but as it ages, it develops a sweeter, more earthy aroma.

Ambergris can often sell for $20-$50 a gram as it is quite rare and highly sought after.

In January of this year a man found a 6 pound lump of ambergris while walking his dog on the beach – link.

In August of last year a young boy and his father found a lump while walking on their local beach – link

If you are ever walking along the beach and find a lump of waxy material, take it home with you. You might just have found a piece of very valuable whale excrement.

The Ice Mummies

17 Apr

The Inca Empire was the largest empire in the Americas before the arrival of Columbus. Within Incan culture, human sacrifices were sometimes carried out as offerings to the gods. Child sacrifices were often made in times of famine or before/after important events. The children were taken up to the tops of mountains and killed, or sometimes left to die of exposure (the mountain tops were freezing). This practice was known as ‘capacocha’, and early Spanish settlers mentioned it in their writings. In recent times, preserved remains of some of these children have actually been found by archaeologists. The remains of a child known as ‘Mummy Juanita’ is an example of one of these sacrificed children.

Mummy Juanita was found wrapped in a tapestry by archaeologist Johan Reinhard and his climbing partner in 1995, on Mount Ampato; a dormant stratovolcano in southern Peru. She was around 11-15 years old at time of death, and is thought to have been killed between the years of 1450-1480. Her body was frozen, which led to mummification. Later, two other well-preserved ‘ice mummies’ were found in close proximity to where Mummy Juanita was found. All had been killed by a blow to the head.

Because Mummy Juanita’s body was mummified, her internal organs were so well-preserved that it was possible for scientists to figure out what her last meal had been, even though she died over 500 years ago. She had eaten a meal of vegetables. It was also found that she had suffered from a lung infection shortly before her death. Her skin, hair, clothing and nails were also well-preserved. The tapestry that she had been wrapped in also contained many other Incan offerings; bowls, pins and figurines.

A similar case was found on Llullaillaco, a mountain on the border of Chile and Argentina. Three frozen bodies were found in 1999 by Reinhard and fellow archaeologist, Constanza Ceruti. One of these is known as ‘la doncella’ (the maiden), and her body is amazingly preserved. Here’s some pictures of her:

La doncella was around 15 when she died. She was taken to the top of the mountain and left to die of exposure after being drugged with coca leaves and a type of maize beer. The other two mummies found with her were a young boy and a young girl. The boy was tied up, and died from strangulation, and the young girl was hit by lightning after her death. From testing the hair of the mummies, scientists could determine the diet that the children had lived on, and it was found that the children were fed a rich diet to ‘fatten them up’ before being sacrificed.

While the circumstances of these deaths are sad, these finds have allowed scientists a rare glimpse into the past.

The Suicide Forest

15 Apr

At the base of Mt. Fuji, Japan, there is a forest called ‘Aokigahara’, which is also known as Jukai (the sea of trees). It is a popular tourist attraction due to the presence of icy caverns; however, it is also a popular destination for something much more disturbing. Aokigahara is one of the most popular suicide destinations in the entire world, second only to San Francisco’s Golden Gate Bridge.

On average, approximately 100 suicides occur every year in the forest. Many of the suicides happen right at the end of the financial year, and most are drug overdoses or hangings. Throughout the forest (and also at its entrances), there are signs written in Japanese and English urging suicidal people to get help and think of their families and other loved ones.

There is an annual body hunt to recover dead bodies, but it is not uncommon to wander through the forest and come across bones, old clothes, nooses hanging from trees, suicide notes nailed to trees, and sometimes even creepier things. There are dolls nailed upside-down to trees in certain parts of the forest, which is allegedly an expression of hatred for society in the form of a curse. To add to the weirdness of the forest, it is also eerily quiet. This is due to the lack of wildlife and the density of the trees, which blocks the wind.

So, how did this awful suicide tradition begin? No one is entirely sure, but many think that a book called ‘Tower of Waves’ may have inspired people to think of Aokigahara as a place for suicides. However, its reputation as a suicide destination predates this novel, and Japanese people have associated the forest with death for a long time. The practice of ‘ubasute’ was allegedly carried out in the forest in the past; this was the practice of taking the elderly or sick into remote areas such as mountains or forests and leaving them to die of exposure or starvation. Thus, many believe that the forest is haunted by the spirits of the dead, and it also has an association with demons in Japanese folklore.

Would you visit this forest, or go camping in it? Any other thoughts? Let us know in a comment below.

Venera Space Program

11 Apr

While we initially started this blog to focus on the interesting things on Earth, we soon realized that some of man’s greatest achievements involve our quest for exploration of our solar system. Because of this, we decided to have an ‘Out of this World’ category that  focuses on human achievements and discoveries that are not on this planet. This post will be the first in the category, with more to come soon.

The Venera Space Program was a Soviet attempt to create space probes to gather data about the planet Venus.

The missions began in 1961, with the Venera 1 craft, and ran through until 1984 with Venera 16.

 Venera 11 Lander - NASA

Venera 11 Lander – NASA

Venera 1 & 2

Venera 1 (1961) & 2 (1965) were meant to be pass-by probes that would collect data as they passed Venus. Unfortunately, both missions suffered from telemetry failure before reaching Venus.

The Soviet Union launched several other probes in the early 1960’s, but these were not announced as planetary observation missions.

Venera 3, 4, 5 & 6

Venera 3 was special. Although the Venera crafts 3-6 were all very similar, Venera 3 was the first craft to reach the surface of another planet. This occurred on March 1st, 1966, when the Venera 3 craft crash landed on the surface of the planet. Unfortunately, due to the entry through the atmosphere, all the data probes on board burned up and were unable to record any data.

Venera 4 was able to provide minor information about the atmosphere of Venus. Unfortunately, the hull of the craft was only able to handle 25atm, much less than the 75-100atm pressures on the surface of Venus.

Venera 5 and 6 were sent as atmospheric probes, and were able to record approximately 50 minutes of data before the batteries drained.

Venera 7 & 8

Venera 7 was the first craft to transmit data back from the surface of another planet. It was designed to survive the pressures, but its parachutes failed on entry and it toppled over during the landing. The signal was weak from the craft, but there was enough time for a transmission to be made.

Venera 8 was very similar; it was able to transmit data during its descent, measure sunlight and transmit data for nearly an hour.

Venera 9, 10, 11 & 12

The Venera craft 9-12 were designed to take photos and transmit the data back to Earth. They were all equipped with two cameras, but during the first two missions (9 &10), only one camera each time was able to capture photos due to the other camera’s lens cap failing to release. Venera 11 and 12 suffered worse; neither of the lens caps on these craft were released. Throughout these missions, the craft were operational for between 50 and 110 minutes.

Venera 13 & 14

These two Venera craft were equipped with much more scientific instrumentation. Here is a list of what was on board, taken from Wikipedia.

  • Accelerometer, Impact Analysis – Bison-M
  • Thermometers, Barometers – ITD
  • Spectrometer / Directional Photometer – IOAV-2
  • Ultraviolet Photometer
  • Mass Spectrometer – MKh-6411
  • Penetrometer / Soil Ohmmeter – PrOP-V
  • Chemical Redox Indicator – Kontrast
  • 2 Color Telephotometer Cameras – TFZL-077
  • Gas Chromatograph – Sigma-2
  • Radio / Microphone / Seismometer – Groza-2
  • Nephelometer – MNV-78-2
  • Hydrometer – VM-3R
  • X-Ray Fluorescence Spectrometer (Aerosol) – BDRA-1V
  • X-Ray Fluorescence Spectrometer (Soil) – Arakhis-2
  • Soil Drilling Apparatus – GZU VB-02
  • Stabilized Oscillator / Doppler Radio
  • Small solar batteries – MSB

These probes were similar to the previous probes, but were equipped with surface imaging radar to help with the entry that was obstructed by the thick clouds of Venus’ atmosphere.

Petra – The Rose-Red City

11 Apr

In the country of Jordan, one of the ancient world’s most beautiful cities is still visible today. The entire city, known as Petra, was carved into the side of a cliff-face, and it has been nicknamed the ‘rose-red city’. This is because most of the rock that it was carved into is a light red color. The city is also famous for its evidence of an ancient water management system.

So, who built it?

Petra was built around 2000 years ago to serve as a capital city for the Nabataeans. The Nabataeans were an ancient Arabic people, and they established trade ties with many other groups at the time. Later, during Roman times, Petra was considered to be the capital of the Roman-Arabian world. During this period, the Petra Roman Road was constructed. This was the main entrance to the city, and featured enormous gates.

Unfortunately, during the period of Roman rule, Petra rapidly declined. In 363 AD, an earthquake destroyed a large proportion of the city, and it eventually fell into ruins. ‘Rediscovered’ by the Western world in 1812, it has been a popular Jordanian tourist destination ever since. It has also been classified as a World Heritage site, and it is quite vulnerable due to erosion/weathering and tourist damage. I hope that it can be preserved for future generations to enjoy.

The Mystery of the Flannan Isles

10 Apr

In the Outer Hebrides (a group of islands near Scotland), there is a small island chain known as the Flannan Isles. There are two main islands in this chain; Eilean Mòr and Eilean Taighe, and from 1895-1899, construction on a lighthouse took place on Eilean Mòr. No permanent residents have lived on the Isles since the lighthouse became automated in 1971. Overall, the island chain would be quite unremarkable if it hadn’t been for the mysterious and still-unexplained event that occurred only one year after construction on the lighthouse was finished.

After it was built, the lighthouse was operated by three men; Thomas Marshall, James Ducat and Donald Macarthur. Late in 1900, crew members of a passing ship noticed that something was amiss. The light was not on, which was especially strange given the poor weather conditions. They reported it to the authorities when they arrived at their destination, and a team was sent to the Flannan Isles to investigate. The team immediately realized that something was wrong when no one was there to greet them. All three of the lighthouse keepers had vanished.

The only other seemingly out-of-place thing was a chair that had been overturned in the lighthouse kitchen. Further investigation of the lighthouse and the island showed extensive storm damage to the west landing on the island, so at first, investigators thought that the men may have been washed away in the storm. However, they had kept logs of their activity right up until the morning that they disappeared (15th December), and the storm damage had apparently occurred sometime before this date.

The men were never seen again, and no bodies ever turned up.

Naturally, this strange occurrence led to wild speculation about what may have happened to the three men. Some alleged that one of the men had murdered the others, and then drowned himself out of guilt. It was also claimed that an enormous sea monster had taken them, while others blamed their disappearance on abduction by foreign spies. Some people also claimed that it was the work of malevolent ghosts, and modern theories mention alien abduction.

Some think that a giant sea monster took the men

Some think that a giant sea monster took the men

After an official investigation, the Northern Lighthouse Board came to the conclusion that the men must have been swept away by a freak wave while they were attempting to secure a box of equipment on the west landing, which was damaged in the previous storm (as recorded in their logs).

A more recent theory claims that a kind of geological formation known as ‘geos’ may have been to blame for the disappearance. A geo is an inlet or cleft in the face of a cliff, caused by wave erosion, and sea caves can form at their heads.

Eilean Mòr has many geos along its coastline, and the west landing of the island is actually situated in a geo. This geo terminates in a sea cave. In stormy weather, water could rush into the cave and explode out again. The theory holds that two of the men may have been securing the box on the west landing, while the other kept watch from the lighthouse. Noticing approaching waves, the watcher raced down to warn his colleagues of the impending danger, knocking a chair over in his haste to get out. Upon getting down to the west landing to warn them, he could have been washed out to sea by the water that exploded out of the sea cave, along with his two colleagues.

An example of a sea cave

A very similar theory claims that one man may have been washed out to sea, and the other ran back to the lighthouse to get help. Upon attempting to rescue the man, both remaining men were washed out to sea by a second freak wave.

So, was the disappearance simply a combination of poor weather and bad luck, or did something far more sinister occur? We do know that when the men disappeared, the weather conditions were very poor, so I think that either one of the freak wave/geo theories would make sense. However, we will probably never know exactly what happened, so the mystery remains open to speculation.

Gigantopithecus

6 Apr

From as long ago as 9 million years, all the way up to only 100,000 years ago, an enormous genus of ape roamed around the areas now known as China, India and Vietnam. It’s also possible that they co-existed with early humans. The first species of this genus to be discovered was Gigantopithecus blacki, and was actually found by chance. In 1935, archaeologist Ralph von Koenigswald found some fossilised teeth in a Chinese medicine shop, and realized that they were from an unknown species. The teeth were usually ground up and used as part of traditional medicines.

While a full skeleton for the giant ape hasn’t yet been found, archaeologists can infer their size from dental remains that have been found. So, exactly how big were these apes? Scientists believe that the males could grow up to 10 feet tall, and weighed as much as 1,200 lb. Females were quite a lot smaller, due to sexual dimorphism. Like many other apes, they were most likely quadrupeds (this means that they moved around on four legs).

G. blacki is thought to have lived in Southeast Asia, and dental analysis shows that it probably lived on bamboo and other plants. Furthermore, since the initial discovery of G. blacki, two more extinct gigantopithecus species have been found; Gigantopithecus giganteus and Gigantopithecus bilaspurensis. G. bilaspurensis lived in India, and G. giganteus appears to have lived in northern India and China. Despite its name, G. giganteus was actually about half the size of G. blacki.

Some conspiracy theorists believe that the gigantopithecus apes may still exist today, and are the reason why legends of Bigfoot, yetis and the like exist throughout the world. Unfortunately for proponents of this theory, there is no evidence that this is true. In fact, humans may have actually led to the decline and later extinction of the species, by using valuable resources that the apes needed to survive.

The Island of Snakes

5 Apr

This is one island that I won’t be visiting anytime soon; Ilha de Queimada Grande, otherwise known as Snake Island, is probably one of the scariest places in the world. The uninhabited island is just off the coast of Brazil, and is home to a species of snake known as the Golden Lancehead Viper.

Location of the island just off the coast of Brazil

Location of the island just off the coast of Brazil

The Golden Lancehead, or Borthrops insularis, is not found anywhere else in the world, but this island is teeming with them. Some say that there is one snake per square meter, and others claim an even higher figure. The island is 430,000 square meters, so that’s at least 430,000 snakes.

They aren’t small snakes, either. The average length of one of these snakes is nearly 30  inches  (75 cm), with some reaching a maximum of 46  inches (116 cm). To make matters worse, they are one of the most venomous snake species on Earth. It’s really no wonder that the island isn’t used for anything.

The species might actually be at risk for extinction, which is sad for them (and snake-lovers). They are considered to be a critically endangered species, and they face other problems due to interbreeding. Interbreeding has caused a high rate of intersex baby snakes to be born, and these intersex snakes are almost always sterile.

As I said earlier, I would definitely never want to set foot on this island. Unfortunately for crazy thrill-seekers who do want to visit it, the Brazilian Navy has expressly forbidden anyone, except the occasional scientist, from going to the island. This really isn’t surprising, considering that wherever you set foot on this island, there is always a snake (or several) close by.

Leptis Magna

5 Apr

All throughout Europe, there are many beautiful ancient Roman ruins, but there are equally-magnificent and lesser-known ruins on other continents too. A good example of this is Leptis Magna. Leptis Magna is the remnants of a once-great Roman port city, and is considered to be one of the most impressive and unspoiled Roman ruins in the world.

The city ruins are near the coast in the African country of Libya, around 80 miles from its capital, Tripoli.

The city was founded by the Phoenicians around 3000 years ago, and was originally called Lpqy. During the reign of the Roman Emperor Tiberius, it became a thriving trade city. Then, from the year 193 onwards, it became one of Roman Africa’s most prominent cities. This was because the Roman Emperor at that time, Septimius Severus, was actually born in Leptis Magna, so he naturally favoured his home-city over others. Severus enlarged the city, and as a result Leptis Magna contains many Roman-inspired buildings; forums, a theatre, public baths, marketplaces and monuments, to name a few.

Eventually, the city was ransacked by the Vandals, and later by the Berbers. Byzantine Empire general Flavius Belisarius tried to re-establish it as a provincial Byzantine capital, but the city didn’t recover from the destruction that previous raiders had caused. By the year 650 AD, the city was mostly abandoned.

Libya isn’t the easiest country to visit due to its political instability, but Leptis Magna would certainly be a wonderful place to see. Archaeologists have still not finished excavating the ruins, so it will also be interesting to see what else ends up being discovered in the future.

Giant’s Causeway

4 Apr

The Giant’s Causeway is located on the north-east coast of Ireland in a place called County Antrim. It consists of approximately 40,000 interlocking basalt columns that formed due to a volcanic eruption.

Giant's Causeway - Source

Giant’s Causeway – Source

Rather than paraphrase Wikipedia’s explanation on the formation I figured I would copy it here as it provides a good, easy to understand overview:

“Some 50 to 60 million years ago, during the Paleogene period, Antrim was subject to intense volcanic activity, when highly fluid molten basalt intruded through chalk beds to form an extensive lava plateau. As the lava cooled rapidly, contraction occurred. Horizontal contraction fractured in a similar way to drying mud, with the cracks propagating down as the mass cooled, leaving pillar-like structures, which are also fractured horizontally into “biscuits”. In many cases the horizontal fracture has resulted in a bottom face that is convex while the upper face of the lower segment is concave, producing what are called “ball and socket” joints. The size of the columns is primarily determined by the speed at which lava from a volcanic eruption cools”

There was an old legend that described the formation as the result of an ancient giant ‘Benandonner’ tearing it up so that the great warrior ‘Fionn mac Cumhaill’ could not follow him. The story goes that the giant challenged Fionn and went to his house seeking him out. Not wanting to fight, Fionn and his wife came up with the idea to dress Fionn up as a baby. When Benandonner came to the house, Fionn’s wife told the giant he was out but he would be back shortly and he could wait if he wished. She showed the giant Fionn’s baby and after seeing how big he was the giant feared Fionn would be bigger. He ran away and tore up the causeway so Fionn could not follow him. There are a few slight variations on this story but this is the general outline.

These basalt structures are not unique to the Giant’s Causeway. There are many other locations with similar features around the world. There are two interesting features located at this spot, though. They are the Chimney Stack and the Giants Boot, shown below.

Mount Mihara – The Most Depressing Volcano in the World

3 Apr

The geographical region that contains Japan and its surrounding areas is infamous for its occurrences of tectonic and volcanic activity, and Mount Mihara is an example of this.

Mount Mihara’s peak from a distance. Source: http://wikitravel.org/shared/Image:IMG_4759.JPG

An active, 2500-foot tall ‘stratovolcano’, it is located on the island of Izu Ōshima, around 100 kilometers south of Tokyo. Stratovolcanoes are tall, conical, and most commonly formed at subduction zones. Mt. Mihara erupts quite frequently, with major eruptions occurring every 100-150 years. During the last major eruption, in 1986, the entire island’s population had to be evacuated by the military, and the plume created by the eruption was 16 kilometers high in the air.

Diagram of a subduction zone and stratovolcano

So, what exactly is so depressing about Mt. Mihara? Well, the story starts in the 1920’s, when several people committed suicide at the volcano. From a certain point at the top of it, it was actually possible to jump straight into the lava. In 1933, a young student named Kiyoko Matsumoto also committed suicide by leaping into it, and this sparked a horrifying trend.

Within the year, almost 1000 people had committed suicide at Mt. Mihara, and when this trend continued for a few more years, Izu Ōshima became known as the ‘Suicide Island’. Eventually, Japanese authorities had to build a large wire fence around the jumping-off point, to prevent any more suicides.

Lava is so dense that if you jumped into it, you would not sink directly into it; instead, you would float. It is so hot that a person would essentially be cooked to death in their own steam, which is created from the body’s water vaporizing as it comes into contact with the lava flow.

That sounds like an incredibly awful way to die, and I have no idea why it became such a trend! Let’s hope that it doesn’t start up again.

The Eye of Africa

3 Apr

The ‘Eye of Africa’ (also known as the Eye of the Sahara) lies within the large east-African country of Mauritania, out in the Sahara Desert. Properly known as the Richat Structure, it is easy to see where its nickname comes from. Looking at it from above, it looks a lot like a big blue eye staring out of the ground. Here’s a picture of the Richat Structure:

It is about 40 kilometers in diameter, and as you can see from the above picture, it is highly visible in satellite pictures.  So, how was this geological wonder formed? Researchers aren’t entirely sure. It was initially thought to have formed as the result of an asteroid impact, but scientists haven’t found any evidence for extraterrestrial involvement, other than its circular appearance.

Zoomed-in image of the Richat Structure from Google Maps

Geologists now believe that it is most likely to be a very symmetrical ‘geologic dome’. Wikipedia’s summary of a dome is this:

In structural geology, a dome is a deformational feature consisting of symmetrically-dipping anticlines; their general outline on a geologic map is circular or oval. The strata in a dome are upwarped in the center; if the top of a dome is eroded off, the result will be a series of concentric strata that grow progressively older from the outside-in, with the oldest rocks exposed at the center.’

No matter what led to the creation of it, the Richat Structure looks amazing, and I’m hoping that I will get to go and visit it one day.

It’s quite hard to imagine that only a few thousand years ago, there were lands on which people lived that have now completely disappeared into the ocean. But, this is exactly what happened to the area known as ‘Doggerland’.

Up until around 8500-8200 years ago, Doggerland was a large stretch of dry land that linked the European mainland to where the British Isles are today. Here’s a picture to show where it was, compared with what the area looks like today:

So, what happened to Doggerland, and how do we know about it?

Archaeologists first started to think that the area may have originally been above sea level in the early 1900’s, when fishing boats in the area would occasionally dredge up the remains of animals that had lived in Europe in prehistoric times, including mammoths and lions (yes, Europe used to have lions!). Plant remains were also brought up and studied by paleobiologists, who found them to be peat from when the land was above sea level and mostly tundra.

To add further interest, prehistoric tools and weapons used by ancient peoples were also found. Archaeologists now believe that Doggerland was occupied by humans during the Mesolithic period (this period started around 10,000 years ago), up until it started to disappear underwater. In fact, some think that it may have been one of the richest hunting and fishing environments available to European humans at the time.

Whilst surveying the area for petroleum, oil-company geologists produced seismic surveys of the land beneath the waves, and in 2012, the Royal Academy of London presented the results of the surveys along with all the artefacts that have been found so far. The seismic surveys allow researchers to see what the land looked like while it was still above sea level, and even Doggerland’s ancient river systems have been mapped in 3D. The largest of these rivers is known as the ‘Shotton River’.

In regards to the disappearance of Doggerland, researchers believe that at the end of the last glacial period, sea levels began to rise dramatically as the climate warmed up. Due to this, Doggerland was eventually submerged under the North Sea, and the British Isles were separated from the European mainland. This probably all happened around 8500 years ago.

Another recent theory claims that after already losing some land to rising sea levels, Doggerland may have become completely submerged as the result of a tsunami that hit the area 8200 years ago. This tsunami was caused by an event known as the ‘Storegga Slide’. It is named this because the event was a massive underwater landslide, occurring off the coast of Norway. The resulting tsunami would have been devastating to Mesolithic people who still lived on Dogger Bank, and after this event, British Mesolithic populations would have been totally separated from the rest.

One part of Doggerland actually remained for quite a while longer. An island known as ‘Dogger Bank’ emerged when the rest went underwater. Dogger Bank was an upland hill area of the original Doggerland, so the sea levels didn’t rise high enough to cover it. Eventually, however, Dogger Bank also disappeared into the ocean, and this probably happened around 7000 years ago. Here is a map that shows us where Dogger Bank is now:

It is fascinating to think that once-populated lands are now totally underwater. Geologists and archaeologists really have the most interesting jobs sometimes!

Derweze – The Door to Hell

31 Mar

In the Karakum (or ‘Black Sand’) Desert, which covers much of the central-Asian country of Turkmenistan, one of the strangest-looking natural gas deposits in the world sits outside of Derweze village. It is a large crater, with a diameter of 230 feet.

It is known to the locals as the ‘Door to Hell’, for reasons that become quite obvious when you look at it. The area also smells quite strongly of sulphur, which is quite a ‘hellish’ smell. Here’s some pictures of it:

If there actually was a doorway to hell, then this place really does resemble how most people would picture it. Why does it look like this, though?

Turkmenistan is known for its natural oil and gas reserves. In fact, it has the fourth-largest natural gas reserves in the world. In 1971, some scientists investigated the field near Derweze to see if they could drill for oil. Upon realising that the field was actually a very large natural gas field, they decided to store the gas, and started drilling operations to get to it. Unfortunately, the ground that they were drilling collapsed and formed a large crater, which released methane gases into the air. Worried that the methane would affect the local population and nearby environment, the scientists decided to burn the gas off. This was considered to be a normal way of getting rid of dangerous gases, and they figured the burning would only last a few days.

It didn’t burn for a few days, though, in fact, it kept burning for 40-odd years. Even today, it is still burning! The hole really does look like some kind of doorway to a fiery underworld, especially at night-time.

So, now you know why it looks like this. I think it would be a great place to visit, but I might never be able to. This is because, as of 2010, Turkmenistan’s government is taking measures to have the hole closed so that it doesn’t influence other natural gas drilling efforts in the region. Either way, the ‘Door to Hell’ is still probably one of the coolest things I’ve ever seen!

What was the Tunguska Event?

28 Mar

Early in the morning of June 17th, 1908, an enormous explosion rocked a remote Siberian area of Russia known as Krasnoyask Krai. The explosion was so massive that it leveled an entire forest of 80 million trees, and it is estimated that it was more than 1000 times more powerful than the atomic bomb that was dropped on Hiroshima during World War II. The epicenter of the explosion was in a swamp near the Podkamennaya Tunguska River, so the event became known as the Tunguska Event.

Luckily, despite the size of the event, it is thought that only one person was killed by the blast (although, not so lucky for the poor man who was killed). This was due to the sheer remoteness of the area that was hit. A lot of people did see it happen, though. Witnesses from areas much farther south claimed that they saw something extremely bright and pale blue moving across the sky, and a few minutes later there was a bright flash accompanied by a thunderous sound. A shockwave, which would have registered at 5.0 on the Richter scale, caused people to be knocked off their feet hundreds of kilometers away.

So, what actually caused this massive explosion? There are several theories. Some have claimed that it may have been caused by the release of natural gases from the Earth’s crust, and others proposed that the explosion may have been a nuclear one; caused by deuterium in a comet undergoing nuclear fusion as it entered the Earth’s atmosphere. Another theory claimed that it was caused by a black hole passing through Earth. And, of course, a lot of people have brought up theories involving UFOs and aliens, especially since as the event is referenced in pop-culture quite a lot.

However, the most widely-accepted explanation is that a large meteoroid or comet caused it, exploding just above the Earth’s surface. This would explain the lack of an impact crater in the area. If this is true, then it was the largest impact event on or near the Earth in modern history. Chemical analysis of soils in the region showed that parts of it contained materials of extraterrestrial origin, further supporting this impact theory.

Despite the fact that the Tunguska Event is still technically unexplained, I would agree that the impact event theory seems to be the most likely. I think it would be even more interesting if there were a more mysterious explanation, though! It’s also very fortunate that it happened in such a remote area, because if it hit a populated area, then the aftermath would have been far worse.

Bog Bodies

28 Mar

Depending on certain variables, human decomposition is generally a very short process, and a dead body buried underground will normally be completely skeletonized in a maximum period of 50 years. If left out in the open, a body will decompose much faster than this. However, the mummified remains of bodies found in peat bogs, known as ‘bog bodies’, can be up to thousands of years old and almost perfectly preserved.

Peat bogs are most prevalent in cold, temperate areas of the Northern Hemisphere (it is possible for them to occur in the Southern Hemisphere, but they are much smaller and less common), and thus, all the bog bodies located so far have been in Northern Europe and North America. Not all are well-preserved, but many still have intact hair, skin and internal organs. So, how is this possible? And, how did the bodies get there in the first place?

The water in peat bogs is cold, acidic, and lacks oxygen, and combined, these factors lead to amazing tissue preservation. Also, tannin (a compound present in tea – this is the stuff that can stain your tea-cups) in the bogs leads to the darker appearance of the skin, and has anti-bacterial properties that aid in the preservation. Unfortunately, the acid in the bog water often destroys the bones, as it dissolves the calcium phosphate in them, leaving only the tissue and hair preserved.

Because of the good soft-tissue preservation, the stomach contents of the bodies can be analysed in some cases, which tells us something about the diets of people during whichever period they lived in. In cases where bones have been preserved, archaeologists can tell what kinds of activities the person engaged in, and even if they were right-handed or left-handed! Also, forensic techniques have been applied to some of the bodies in order to reconstruct their appearances. Here’s some examples:

The bodies that have been recovered from peat bogs cover a very wide time span, with some dated from 10,000 years ago and others all the way up to World War II. It seems that some of the bodies belonged to unlucky individuals who simply fell in, but many others appear to have died violently, after which they were thrown into the bogs. This may have been as punishment for a crime, or, perhaps it was human sacrifice. The majority of the violently-killed bodies have been dated to the Iron Age (this began around 3000 years ago, and lasted about 500 years), so some archaeologists believe that Iron Age groups may have had this means of execution or ritual sacrifice as a cultural tradition.

Overall, the bog bodies are not only interesting, but very useful to historians, archaeologists, and anthropologists, as they yield so much useful information in regards to past peoples who lived around the bogs. For more reading on the topic, check out

The Devil’s Triangle

27 Mar

Almost everyone knows stories about the Bermuda Triangle; the sea between the three points of Bermuda, Florida, and Puerto Rico which is apparently responsible for the demise of many ships and planes due to ‘mysterious circumstances’. However, hardly anyone has heard of the allegedly equally-dangerous Devil’s Triangle (otherwise known as the Devil’s Sea or the Dragon’s Triangle).

This particular ‘triangle’ has apparently claimed the lives of many people over the years, and stories hold that some supernatural force causes ships to disappear. There have been claims that other paranormal events occur in this region too, like time lapses and electronic malfunction. Some people also believe they have seen UFOs in the area. Also, the ‘Dragon’s Triangle’ name apparently originates from ancient tales of fire-breathing dragons being in the area.

So, where exactly is the Devil’s Triangle? The location differs depending on who you ask, but it is thought to be somewhere in the Pacific Ocean, anywhere between 100 – 1300 km from Japan. That’s not exactly specific… however, most believe that the Devil’s Triangle is close to the Izu Islands, a chain of islands not too far south of Tokyo.

I wasn’t able to find any sources as to where the legend first definitively arose, aside from the ancient dragon legends, but a lot of it had to do with a book written by Charles Berlitz, called ‘The Dragon’s Triangle’. In this book, Berlitz claimed that Japan had officially declared the area a danger zone after they lost 700 people from military ships during 1952-1954. The ships apparently vanished into thin air, at which point Berlitz claims the Japanese government sent a research ship with 100 people to investigate. This research vessel promptly vanished too.

Now, this legend would be very spooky… if there were actually any truth to it. The oceans around Japan are known for their seismic and volcanic activity, so disappearances of ships/boats isn’t exactly an abnormal occurrence. The ‘fire-breathing dragons’ of the ancient legends could have just been volcanoes.

Also, it seems that Berlitz sensationalized the whole issue, along with simply making stuff up. The research ship, the Kaiyo Maru No. 5, actually only had 31 people aboard, and was found to have been destroyed by a volcanic eruption while it was investigating an underwater volcano. The military vessels that Berlitz referred to were actually just fishing vessels, and he conveniently ignored the fact that hundreds of fishing vessels are lost over the years in all different regions of the Pacific, not just the Izu Islands region.

I love reading about weird and creepy things, so it would be great if the stories surrounding the Devil’s Triangle were true. But, unfortunately, it seems like it is just another story that was made up to entertain people, or perhaps warn them about the real (seismic/volcanic) dangers of the area.

Amazing Genetics – Are Some People Immune to HIV?

27 Mar

HIV, the virus that leads to AIDS, has led to the deaths of over 30 million people since its discovery. Something that many people may not be aware of is that scientists and doctors classify different species and subtypes of the virus. There are two ‘species’; HIV 1 and HIV 2, and these are further divided into subgroups, and then subtypes within the subgroups.

So, put very simply, there are many different ‘strains’ of the virus, with each having varying rates of transmission, transmission pathways, and resistance to treatment. Many of these forms of HIV bind to a certain protein on white blood cells in order to infect a person, and this protein is known as CCR5.

Amazingly, however, some people are naturally resistant to these forms of HIV, because they carry a mutation. So, what is this mutation, and how does it work?

Basically, these people carry a mutated version of the CCR5 gene, known as CCR5-delta-32. This mutation results in the ‘deletion’ of part of the CCR5 gene, which leads to the virus being unable to bind to the protein and enter the white blood cells like it normally would.

It is thought that this mutation arose in Europe, and around 10% of Europeans are thought to carry it, along with this resistance to certain forms of HIV. Furthermore, it has also been suggested that the mutation confers resistance to smallpox, and may have actually originated and spread via natural selection during the plague period in Europe’s history, which challenges the assumption that the plague period was caused by the spread of bubonic plague. Apparently, the normal frequency of the mutation’s occurrence is 1 in 20,000, but the plagues are thought to have increased the rate to 1 in 10 amongst Europeans. Of course, people from other regions can also carry the gene mutation, but it is a lot rarer for them.

Interestingly, a man suffering from leukaemia and AIDS was cured of both illnesses when given bone marrow transplants as part of his cancer treatment. It turns out that the donor of the bone marrow was a carrier of the ccr5-delta-32 mutation, and this has led scientists to believe that the mutation could be used as a potential cure for HIV infections.

The Bystander Effect

26 Mar

This post is not going to be on anything physical, but instead a psychological phenomenon called the ‘The Bystander Effect’.

It refers to situations in which an individual is unlikely (or less likely) to provide help or assistance to someone in need while there are other people around. Studies have shown that the probability of help someone will receive is inversely related to the number of bystanders.

Wikipedia provides a nice summary for the origin of research in to this effect (sourced below):

“The bystander effect was first demonstrated in the laboratory by John Darley and Bibb Latané in 1968 after they became interested in the topic following the murder of Kitty Genovese in 1964. These researchers launched a series of experiments that resulted in one of the strongest and most replicable effects in social psychology. In a typical experiment, the participant is either alone or among a group of other participants or confederates. An emergency situation is then staged. The researchers then measure how long it takes the participants to act, and whether or not they intervene at all. These experiments have often found that the presence of others inhibits helping, often by a large margin. For example, Bibb Latané and Judith Rodin staged an experiment around a woman in distress in 1969. 70 percent of the people alone called out or went to help the woman after they believed she had fallen and gotten hurt, but when there were other people in the room only 40 percent offered help.

Source:  Meyers, David G. (2010). Social Psychology (10th Ed). New York: McGraw- Hill. ISBN 978-0-07-337066-8.

I first heard about this phenomenon a few years ago; it jogged my memory and I remembered when I had once experienced the bystander effect. I was driving a friend home at approximately 3pm, and on the way we passed a bus stop where there was a man waiting. He was wearing a hoodie and other baggy clothes that looked quite dirty, which was nothing unusual for the area it was in. About 45 minutes later during my trip home, I passed the same bus stop and the man was lying down on the bench. It seemed odd, because buses past that stop are frequent so he shouldn’t have had to wait long. There were also plenty of people walking past the stop. I went home and walked to a cafe near the bus stop to get a coffee. The man was still there. I decided that there were plenty of other people walking past, so if something was wrong someone would have done something about it. I went home and forgot about it. Later that evening I turned on the news to a camera-shot of the bus stop, with a news presenter saying that a man had overdosed and was rushed to hospital after he had been seen lying down at the stop for a couple of hours. He survived the incident, and was lucky that people living across the road from the bus stop noticed and called the emergency services.

I was of the mentality that there were plenty of people walking by and if the man really needed help, someone else would have helped out already.

In attempting to explain the bystander effect, scientists have come up with 3 steps that must occur to overcome it, and these are outlined below.

Noticing:

This step requires that the bystander notices the situation. With a limited number of people around, an individual is more likely to take note of what is occurring, whereas a large group of people in the area will draw an individual’s attention away from the situation.

Interpretation:

This step can only occur after a bystander notices the situation. They need to interpret what is happening and decide whether it is an emergency situation or not. We often look at the reactions of people around us to help form our own interpretation of an incident. The problem is that everyone is looking around trying to make an interpretation, the fact that no one is moving means everyone stands there and figures it must be OK.

Taking Action:

This is where things can really fall apart, even if the first two steps have been overcome. Even if someone notices the situation and interprets it as an emergency, they must take action.  The thing is, people fall victim to the diffusion of responsibility, they think that others will step in and help, or that other people standing by might be more qualified to provide assistance. Whatever the reason, as a group, we fail to act.

Looking back on my account, I noticed the incident, interpreted it as nothing unusual and failed to act. 

After learning about this phenomenon, I have been able to act accordingly in similar situations. I was out shopping one day when I noticed an old lady lying on the ground. There were a few other people standing around but not really doing anything. I walked over and as I did, a few other people joined me. It turns out that the lady had had a fall and was a little dazed. It was hot out so we got her some water while someone phoned an ambulance.

Hopefully, you now have an understanding of what is going through your mind when you see a situation and are trying to make a decision on whether or not to act. Even just walking towards the situation could trigger others to do the same, in which case someone who may need help will get it.

The Mysterious Hinterkaifeck Murders

26 Mar

In Germany, 1922, the murders of six people at the Hinterkaifeck farmstead shocked the nation. This wasn’t just because of the gruesome nature of the case, but also because the case was so incredibly weird, and it remains unsolved to this day.

Here is a photo of how the farm appeared back then (it has since been demolished):

Now, for some background to the case; the Gruber family, consisting of Andreas and Cäzilia Gruber, their daughter Viktoria, and her two children Cäzilia (7) and Josef (2), and their maid, Maria Baumgartner, lived permanently at Hinterkaifeck, which was situated next to a forest. Maria was new to the farm, having only just arrived that day as a replacement for another maid. Interestingly, the previous maid had left claiming that she thought the farm was haunted.

Whilst no one is certain as to exactly what happened, it appears that on the night of March 31st, 1922, someone managed to lure all of the family members (except Josef and the maid, Maria) into the barn, one by one, and murdered them all with an axe. Horrifyingly, the autopsy showed that young Cäzilia had been alive for quite some time after being attacked, tearing her own hair out as she lay dying in the barn. The killer then went into the house and killed Josef and Maria in their beds.

The family was noticed as missing several days later when none of them had been seen for a few days, and young Cäzilia had not attended school.  Neighbors went to check on them and discovered the bodies. After extensive police investigations, a viable suspect was not found. And, as if the situation wasn’t already horrible enough, it actually gets worse.

Neighbors recalled that just a few days before the murders, Andreas Gruber had mentioned a strange occurrence to them. He claimed that he had found footprints in the snow, leading from the forest’s edge to the house, but there were no footprints leading back. He also thought he had heard strange sounds coming from the attic. A particularly terrifying theory that stems from this is that someone may have sneaked into the house, lived undiscovered up in the attic for a few days, and then come out to murder the house’s occupants. To further add to this theory, in the days that the bodies were certainly lying dead in the barn, neighbors reported that they had seen smoke rising from the chimneys. Also, someone had been feeding the farm’s cattle. So, if someone had done this, it also seemed as if they had stayed for several days after the murders to take care of the place.

This theory leads to many questions.  Was it just one person, or more? Why did this person (or people) want to kill the family? How did they sneak into the house? How did they lure the family into the barn, one by one? Why would they stay for several days later, and take care of the farm?

Overall, taking these questions into account, the case of the Hinterkaifeck murders is terrifying to comprehend, and it remains as one of Germany’s most mysterious unsolved cases. It is unlikely that we will ever really know what happened, which seems to make it even scarier.

The Disappearance of Harold Holt

26 Mar

Harold Holt was the Prime Minister of Australia for nearly two years from January of 1966, up until his disappearance in December of 1967.

The strange thing about Holt’s disappearance is that his body was never recovered, and this has led to different theories surrounding what actually happened.

Harold Holt, the 17th Prime Minister of Australia. Photo taken during the 1966 elections.

First of all, what do we know?

On Sunday the 17th of December, 1967, Holt and a group of friends, along with two bodyguards, made a trip from Melbourne to Port Phillip Heads to watch part of a solo circumnavigation of the globe, by Alec Rose in his yacht the ‘Lively Lady’. Around midday, the party made their way to Cheviot Beach, which lies on the eastern arm of Port Phillip Bay. This was one of Holt’s favorite swimming and snorkeling locations despite its reputation for strong rips and currents. Holt was described by his biographer Tom Frame as having “incredible powers of endurance underwater”, most likely due to Holt’s experience as a scuba diver. Despite pleas from the rest of the party, Holt made his way into the water. Not long after entering the water, the party lost sight of Holt. His friends raised the alarm, and a search began with a large group of police, Royal Australian Navy divers, helicopters from the Royal Australian Airforce, army personnel and local volunteers.

Two days later, on the 19th of December, the Australian Government made an announcement that Harold Holt was presumed dead. From here on in is where the theories start.

For the most part, it is generally accepted that Holt fell victim to the strong currents and rips in the area and his body was dragged out to sea before anyone could notice. There are no real ‘loose ends’ with this theory. Holt had recently suffered a flare up of a recurring shoulder injury that caused him a lot of pain. It is quite likely that he was not up to his usual levels of fitness and grew tired fighting the currents or rips. The main issue people have with this idea is that with such a large scale search, it is surprising that his body was not recovered.

Other theories start to speculate on the idea that he committed suicide. This theory has been rejected by  Holt’s own son Sam, his biographer Tom Frame (mentioned before), and  Malcolm Fraser, Holt’s Cabinet Minister at the time. This theory arose after reports that Holt was suffering from depression prior to his disappearance.

Some theories started bordering on conspiracy. There is the idea that he faked his own death to run away with a mistress,  was abducted by a UFO, or kidnapped/rescued by a Chinese submarine, depending on whether or not you think he was a Chinese spy.

Although it seems most likely that the strong rips and currents were  to blame for Holt’s disappearance, the idea that this was an Australian Prime Minister who may have been involved with something more sinister has piqued the curiosity of imaginative minds for many years. Unfortunately, it is doubtful that we will ever know exactly what happened in this tragic case.

Wave Rock

26 Mar

There are many well-known natural formations all over the world; The Grand Canyon, Niagara Falls and Mt Everest, to name a few. In Australia, there is a particularly spectacular formation that many of our readers may not be aware of, due to its fairly remote location. I am referring to what is known as ‘Wave Rock’; an enormous rock formation in south-eastern Western Australia, which is the largest state in Australia.

Located 3km (or about 2 miles) from the small town of Hyden, this natural geological formation attracts approximately 140,000 tourists a year. The rock itself is a large granite formation that has been dated to 2.63 billion years old, and was created through complex geological processes. As you can see from the picture below, it closely resembles an ocean wave, hence the name, and is nearly 50 feet (14m) high and 350 feet (110m)  across.

Wave Rock. It stands 14m high and close to 110m long.

While there are no creepy mysteries relating to Wave Rock itself, the local indigenous people stayed clear of the area for fear of the spirit ‘Mulka’.

Here is the story of Mulka sourced from the Wave Rock website

Legend of Mulka’s Cave

“The name Mulka comes from an Aboriginal legend associated with the cave. Mulka was the illegal son of a woman who fell in love with a man with whom marriage was forbidden according to their law.

It was believed that as a result of breaking these rules she bore a son with crossed eyes. Even though he grew to be an outstandingly strong man of colossal height, his crossed eyes prevented him from aiming a spear accurately and becoming a successful hunter.

Out of frustration it is said Mulka turned to catching and eating human children, and he became the terror of the district. He lived in Mulka’s cave, where the imprints of his hands can still be seen, much larger and higher than that of an ordinary man.

Apparently, his mother became increasingly concerned about him. When she scolded him for his anti-social behaviour he turned on his own mother and killed her. This disgraced him even further and he fled his cave, heading south.

The Aboriginal people of the area, outraged by Mulka’s behaviour, then tracked down this man who had flouted all the rules. They caught him near Dumbleyung, 156km south west of Hyden, where they speared him to death. Because he did not deserve a proper ritual burial, they left his body to the ants: a grim warning to those who break the law.”

So, how did this formation come to be? As previously stated, the geological processes that led to the formation of Wave Rock are quite complex, but I will attempt to break it down to a simple, easier to understand explanation for our readers. Basically, Wave Rock is a part of a much larger rock known as Hyden Rock, and the shape was created by continuous erosion of the softer rock beneath the upper edge, in the process of weathering. This occurred over many millions of years. Eventually, this resulted in an ‘undercut’ base with a rounded overhanging shape, and ended up in the wave shape that we see today.

Having lived in Western Australia most of my life, I have visited wave rock numerous times. If you ever decide to visit Western Australia, I highly suggest making the effort to go and see the rock and some of the Australian countryside whilst you are there.

Dudley Town

24 Mar

In a forested area near Cornwall, a small town located in the picturesque Litchfield County, Connecticut, there is an abandoned old settlement known to locals as Dudley Town. Although it was never officially considered to be a town, several families lived there in the past. The area was first settled by a Thomas Griffis in the 1740’s, closely followed by several members of the Dudley family, whom the settlement was named for.  Locals claim that Dudley Town is now one of the most haunted abandoned towns in all of New England. Furthermore, it is actually illegal to visit the place, which adds to the mysteriousness of the case.

So, what’s with all the legends and secrecy surrounding Dudley Town? It all began when the town was completely abandoned by 1899, and the surrounding forest started to creep back in, leaving the settlement in ruins. Local legend has it that the inhabitants succumbed to some type of ‘madness’, while others died horrible, violent deaths. Also, according to hikers who have visited the place, the woods around the settlement are allegedly eerily silent, with birds and animals refusing to go anywhere near it. Hikers have also reported seeing strange orbs floating around the area.

While all of this makes for a good ghost story, historical researchers have found that most accounts of Dudley Town’s ‘haunting’ were simply made up for entertainment. Other less-imaginative hikers have claimed that the forest near the area is perfectly normal, and there are plenty of birds and other wildlife around. The land was most likely abandoned due to the land’s poor location and soil fertility compared with areas much further west. But, why is it illegal to visit the site?

Trespassers are heavily fined if they are discovered by the police that patrol the area. This makes it seem even more mysterious; why go to so much effort to guard an abandoned town? What are they hiding? The answer is actually simple enough. The land where the settlement ruins stand is now private property belonging to the Dark Entry Forest Association, who have planted many trees in an attempt to create a necessary ecosystem for wildlife, and do not want visitors encroaching on the land and disturbing this ecosystem.

As I said before, the idea that Dudley Town is haunted, with all its previous occupants cursed by some evil spirits, makes for a very good creepy story for people to tell others around a campfire. While there isn’t really any truth to it, I would certainly still like to be able to visit it myself… just to make sure.

Ancient Monsters of the Deep Seas – Megalodon

24 Mar

To all the shark-lovers out there, this will definitely interest you. To everyone else… well, try not to have nightmares about this coming towards you while you’re swimming.

C. megalodon, or simply ‘megalodon’, is the name given to a terrifyingly-large shark species that roamed our oceans from around 28 to 1.5 million years ago. Although it is now extinct, and has been for millennia, the megalodon remains one of the most powerful and dangerous predators ever to have existed.

Fossil remains show that the megalodon was also one of the largest predators throughout history, with some measuring up to nearly 70 feet long. Their serrated teeth were disturbingly large; here is a picture of one of their teeth next to those belonging to great white sharks.

Imagine being bitten by one of those! Here’s another picture of a reconstructed megalodon jaw:

The location of found megalodon fossils shows that they lived in oceans all over the world, and they would have had quite an effect on other marine creatures living at the time, due to their predatory nature and extreme size.

Scientists are unsure as to what led to the demise of the megalodon species, but there are a few theories. New competition may have emerged, or there could have been a decline in food supply. Being so enormous, they would have required a lot of food, so a decline in available prey could easily have crippled them. Another theory is that global cooling of the oceans may have had an effect on the megalodons, as they preferred to live in warmer waters. It could well have been a combination of all these factors.

Whilst it is sad that the megalodon eventually became extinct like so many other ancient species, I bet that the majority of people in the world are glad that this isn’t something that they have to worry about running into while out swimming or diving!

Cenote Angelita’s Underwater River

24 Mar

An underwater river? How does that work? It seems impossible, but somewhere in Mexico, there is an underwater cave that has exactly that; an underwater river. The place I am describing is known as Cenote Angelita, and photographer/scuba diver Anatoly Beloshchin has managed to capture some amazing photographs of this river.

Firstly, let’s have a look at the logistics of a ‘cenote’. Cenotes, common to Mexico, are basically deep holes in the ground that result from the collapse of bedrock, and the groundwater is exposed from its normally subterranean hiding spot. These cenotes attract daring cave divers from all over the world, especially in the Yucatan Peninsula of Mexico.

Cenote Angelita is a special kind of cave, because of the especially beautiful scenery that awaits scuba divers. Here are some of Anatoly Beloshchin’s photographs of the cave:

As you can see from the pictures, it appears that although the divers are already underwater, there is a river at the base of the cave. This river even seems to come complete with trees; branches and leaves are visible around it. So, how is this possible?

Well, the ‘river’ isn’t actually a river. It’s a large layer of hydrogen sulphide, and just has the appearance of a real river. Either way, it makes for some incredible scenery, and is definitely a spot worth looking at if you are a trained scuba diver. I am not a trained scuba diver myself, but images like this definitely make me want to go and learn how to do it!
