10 Mysterious Places Around The World That Are Hard To Explain... Even For Scientists
Earth never stops surprising us. Every corner of the planet offers some sort of natural peculiarity with an explanation that makes us wish we'd studied harder in junior high Earth science class.
Some of these sites are challenging to get to; others are busy tourist destinations. They keep natural scientists searching for answers and the rest of us astounded by the secrets and mysteries the world continues to reveal.
Blood Falls, Antarctica
P
Most people won't see Blood Falls in person, but even in photographs, the sight is arresting: a blood-red waterfall staining the snow-white face of Taylor Glacier. Glaciologists and microbiologists have sought to determine what causes the mysterious red flow. They've concluded that the source is a subterranean lake rich in the iron that gives the water its red hue. Stranger still, recent research has revealed microorganisms living 1,300 feet beneath the ice, sustained by the iron and sulfur in the water.
Magnetic Hill, Moncton, New Brunswick
What could possibly cause an automobile to roll backward uphill without power? A magnetic force from within the Earth? Something even more fantastic? Since the 1930s, when the phenomenon of Magnetic Hill was discovered (and almost immediately promoted as a tourist attraction), people have been trying to figure out its riddle.
Surtsey, Iceland
When people try to convince you there's nothing new under the sun, direct them to the Icelandic island of Surtsey. Before 1963, it didn't exist. Then, an underwater volcano in the Westman Islands (Vestmannaeyjar) erupted, and when the activity settled down in 1967, what remained was an island where no island had been before.
Moeraki Boulders, New Zealand
Large spherical boulders -- some measuring 12 feet in circumference -- are scattered on Koekohe Beach on the east coast of New Zealand's South Island. They formed millions of years ago on the ancient sea floor, collecting and hardening sediment and minerals around a core such as a fossil or a shell similar to the way oysters form pearls.
They're not the world's only examples of what geologists call septarian concretions. You can also visit the Koutu Boulders near Hokianga Harbour on the northwestern coast of New Zealand's North Island, for example. Yet the Moeraki Boulders are some of the world's largest. The particulars of their origin and what caused the distinctive cracks inside them are still being studied.
Longyearbyen, Norway
From April 20 to August 23, the sun never sets over Svalbard, a Norwegian archipelago that lies north of Greenland in the Arctic Sea. The phenomenon plays havoc with everyone's body clocks. Is it noon? Is it midnight? After a day or two, it's hard to tell.
Pamukkale, Turkey
What appears to be a Doctor Zhivago-style snowy landscape in southwestern Turkey is actually the result of calcium carbonate deposits from 17 natural hot springs accumulating over thousands of years. Beginning in the late second century B.C., this area near present-day Denizli was a destination for those who sought the therapeutic benefits of the mineral-rich water whose temperature reaches upward of 100 degrees Fahrenheit.
Today, you can see remnants of the baths at the ancient holy city of Hierapolis, but it's the stunning terraces, cliffs and petrified white waterfalls of Pamukkale -- Turkish for "Cotton Palace" -- that give it remarkable natural beauty.
Racetrack Playa, Death Valley, California
How ordinary stones manage to "sail" over the surface of Racetrack Playa in Death Valley National Park is a mystery people have tried to solve since 1915, when a prospector and his wife noticed tracks that seemed to indicate that the stones had somehow traveled across the dry earth. Short of cosmic intervention, the stones required terrestrial forces to move them.
But what forces? The current prevailing theory about the "sailing stones" of Racetrack Playa, presented by a team of physicists in 2011, involves ice that forms around the stones, causing them to move and to leave a trail in their wake. Many visitors still hope for a more mystical explanation.
Eternal Flame Falls, Orchard Park, New York
Behind the cascade of a small waterfall in the Shale Creek Preserve section of Chestnut Ridge Park in suburban Buffalo, New York, you might see what appears to be an optical illusion: a flickering golden flame. Actually, you'll smell it before you see it, and amazingly, it's real, fueled by what geologists call a macroseep of natural gas from the Earth below.
A geological fault in the shale allows about 1 kilogram of methane gas per day to escape to the surface, where, at some point, possibly the early 20th century, a visitor had the idea to set it alight. The water occasionally extinguishes the flame, but there's always another hiker with a lighter to reignite it.
Old Faithful, Yellowstone National Park
Yellowstone National Park claims the highest concentration of geysers of any place on Earth. Geysers are hot springs with plumbing challenges that result in eruptions. More than 300 can be found throughout the park, and none is more famous than Old Faithful. In fact, Old Faithful is the reason Yellowstone was designated a National Park -- the first in the United States -- in 1872.
Its name comes from the perceived regularity of its eruptions, which occur every 55 to 120 minutes and last for two to five minutes. The spectacular eruptions remain a source of fascination for the more than 3.5 million people who visit Yellowstone each year. The fact that the eruptions aren't quite as regular as they might seem -- and that the mean eruption interval seems to be lengthening -- keeps geologists fascinated, too.
Relampago del Catatumbo, Ologa, Venezuela
Thanks to its humidity, its elevation and the clash of winds from the mountains and the sea, the southwestern corner of Lake Maracaibo in Venezuela has the world's highest frequency of lightning activity (250 flashes per square kilometer per year).
More than 200 nights per year, with peaks in May and October, lightning flashes fill the sky -- sometimes 25 or more flashes per minute. To put that in perspective: The National Weather Service classifies anything over 12 strikes per minute as "excessive." Named for the Catatumbo River, which flows from Colombia in to Lake Maracaibo, the Relampago de Catatumbo, or Catatumbo Lighting, has become a highlight for travelers who spend their nights wide awake and wide-eyed watching the spectacle.
7 Wonders of the World
Taj Mahal: Agra, India
This immense mausoleum was built on the orders of Shah Jahan, the fifth Muslim Mogul emperor, to honor the memory of his beloved late wife. Built out of white marble and standing in formally laid-out walled gardens, the Taj Mahal is regarded as the most perfect jewel of Muslim art in India. The emperor was consequently jailed and, it is said, could then only see the Taj Mahal out of his small cell window.
Christ Redeemer: Rio de Janeiro, Brazil
This statue of Jesus stands some 38 meters tall, atop the Corcovado mountain overlooking Rio de Janeiro. Designed by Brazilian Heitor da Silva Costa and created by French sculptor Paul Landowski, it is one of the world’s best-known monuments. The statue took five years to construct and was inaugurated on October 12, 1931. It has become a symbol of the city and of the warmth of the Brazilian people, who receive visitors with open arms.
Great Wall of China: China
The Great Wall of China was built to link existing fortifications into a united defense system and better keep invading Mongol tribes out of China. It is the largest man-made monument ever to have been built and it is disputed that it is the only one visible from space. Many thousands of people must have given their lives to build this colossal construction.
Machu Picchu: Peru
In the 15th century, the Incan Emperor Pachacútec built a city in the clouds on the mountain known as Machu Picchu (“old mountain”). This extraordinary settlement lies halfway up the Andes Plateau, deep in the Amazon jungle and above the Urubamba River. It was probably abandoned by the Incas because of a smallpox outbreak and, after the Spanish defeated the Incan Empire, the city remained ‘lost’ for over three centuries. It was rediscovered by Hiram Bingham in 1911.
Petra: Jordan
On the edge of the Arabian Desert, Petra was the glittering capital of the Nabataean empire of King Aretas IV (9 B.C. to 40 A.D.). Masters of water technology, the Nabataeans provided their city with great tunnel constructions and water chambers. A theater, modelled on Greek-Roman prototypes, had space for an audience of 4,000. Today, the Palace Tombs of Petra, with the 42-meter-high Hellenistic temple facade on the El-Deir Monastery, are impressive examples of Middle Eastern culture
Roman Colosseum: Rome, Italy
This great amphitheater in the centre of Rome was built to give favors to successful legionnaires and to celebrate the glory of the Roman Empire. Its design concept still stands to this very day, and virtually every modern sports stadium some 2,000 years later still bears the irresistible imprint of the Colosseum’s original design. Today, through films and history books, we are even more aware of the cruel fights and games that took place in this arena, all for the joy of the spectators.
Pyramid at Chichén Itzá: Yucatan Peninsula, Mexico
Chichén Itzá, the most famous Mayan temple city, served as the political and economic center of the Mayan civilization. Its various structures – the pyramid of Kukulkan, the Temple of Chac Mool, the Hall of the Thousand Pillars, and the Playing Field of the Prisoners – can still be seen today and are demonstrative of an extraordinary commitment to architectural space and composition. The pyramid itself was the last, and arguably the greatest, of all Mayan temples.

The "Mystery" of the Bermuda Triangle
The five avengers lost on December 5th, 1945 are sometimes known as "The Lost Squadron." (Copyright Lee Krystek, 2011)
|
The Bermuda Triangle (sometimes also referred to as the Devil's Triangle) is a stretch of the Atlantic Ocean bordered by a line from Florida to the islands of Bermuda, to Puerto Rico and then back to Florida. It is one of the biggest mysteries of our time - that perhaps isn't really a mystery.
The term "Bermuda Triangle" was first used in an article written by Vincent H. Gaddis for Argosy magazine in 1964. In the article, Gaddis claimed that in this strange sea a number of ships and planes had disappeared without explanation. Gaddis wasn't the first one to come to this conclusion, either. As early as 1952, George X. Sands, in a report in Fate magazine, noted what seemed like an unusually large number of strange accidents in that region.
In 1969 John Wallace Spencer wrote a book called Limbo of the Lost specifically about the Triangle and, two years later, a feature documentary on the subject, The Devil's Triangle, was released. These, along with the bestseller The Bermuda Triangle, published in 1974, permanently registered the legend of the "Hoodoo Sea" within popular culture.
Why do ships and planes seem to go missing in the region? Some authors suggested it may be due to a strange magnetic anomaly that affects compass readings (in fact they claim Columbus noted this when he sailed through the area in 1492). Others theorize that methane eruptions from the ocean floor may suddenly be turning the sea into a froth that can't support a ship's weight so it sinks (though there is no evidence of this type of thing happening in the Triangle for the past 15,000 years). Several books have gone as far as conjecturing that the disappearances are due to an intelligent, technologically advanced race living in space or under the sea.

Kusche's Theory
In 1975 Larry Kusche, a librarian at Arizona State University, reached a totally different conclusion. Kusche decided to investigate the claims made by these articles and books. What he found he published in his own book entitled The Bermuda Triangle Mystery-Solved. Kusche had carefully dug into records other writers had neglected. He found that many of the strange accidents were not so strange after all. Often a Triangle writer had noted a ship or plane had disappeared in "calms seas" when the record showed a raging storm had been in progress. Others said ships had "mysteriously vanished" when their remains had actually been found and the cause of their sinking explained. In one case a ship listed missing in the Triangle actually had disappeared in the Pacific Ocean some 3,000 miles away! The author had confused the name of the Pacific port the ship had left with a city of the same name on the Atlantic coast.
More significantly, a check of Lloyd's of London's accident records by the editor of Fate in 1975 showed that the Trianglewas no more dangerous than any other part of the ocean. U.S. Coast Guard records confirmed this and since that time no good arguments have ever been made to refute those statistics. So many argue that the Bermuda Triangle mystery has disappeared, in the same way many of its supposed victims vanished.

Even though the Bermuda Triangle isn't a true mystery, this region of the sea certainly has had its share of marine tragedy. This region is one of the heaviest traveled areas of ocean in the world. Both small boats and commercial ships ply its waters along with airliners, military aircraft and private planes as they come to and from both the islands and more distant ports in Europe, South America and Africa. The weather in this region can make traveling hazardous also. The summer brings hurricanes while the warm waters of the Gulf Stream promote sudden storms. With this much activity in a relatively small region it isn't surprising that a large number of accidents occur. Some of the ones commonly connected to the Triangle story are:
The USS Cyclops Sinking
One of the first stories connected to the Triangle legend and the most famous ship lost in the region was the USS Cyclops which disappeared in 1918. The 542 foot long Cyclopswas launched in 1910 and served as a collier ( a ship that carries coal) for the U.S. Navy during World War I. The vessel was on its way from Bahia, Salvador, to Baltimore, Maryland, but never arrived. After it had made an unscheduled stop at Barbados on March 3rd and 4th to take on additional supplies, it disappeared without a trace. No wreckage from the ship was ever found and no distress signal was received. The deaths of the 306 crew and passengers of the USS Cyclops remains the single largest loss of life in U.S. Naval history not directly involving combat.

While the sinking of theCyclops remains a mystery, the incident could have happened anywhere between Barbados and Baltimore, not necessarily in the Bermuda Triangle. Proponents of the Bermuda Triangle theory point to the lack of a distress call as evidence of a paranormal end for the vessel, but the truth is that wireless communications in 1918 were unreliable and it would not have been unusual for a rapidly-sinking vessel to not have had a chance to send a successful distress call before going under.
SS Marine Sulphur Queen Vanishes
The SS Marine Sulphur Queen, a tanker ship carrying molten sulphur, disappeared off the southern coast of Florida in 1963. The crew of 39 was all lost and no wreckage from the tanker was ever found. While the disappearance of the ship is mentioned in several books about the Triangle, authors don't always include that the Coast Guard concluded that the vessel was in deplorable shape and should have never gone to sea at all. Fires erupted with regularity on the ship. Also, this class of vessel was known to have a "weak back", which means the keel would split when weakened by corrosion causing the ship to break in two. The ship's structure had been further compromised by a conversion from its original mission as an oil tanker to carrying molten sulphur. The conversion had left the vessel with an extremely high center of gravity, increasing the chance that it would capsize. The SS Marine Sulphur Queen was all-in-all a disaster waiting to happen and it seems unfair to blame its demise on the Bermuda Triangle.

The Disappearance of NC16002
NC16002 was a DC-3 passenger plane that vanished on the night of December 28, 1948, during a flight from San Juan, Puerto Rico, to Miami, Florida. The weather was fine with high visibility and the flight was, according to the pilot, within 50 miles of Miami when it disappeared with its three crew members and twenty-nine passengers. Though no probable cause for the loss was determined by the official investigation, it is known that the plane's batteries were not fully charged on takeoff and this may have interfered with communications during the flight. A message from Miami to the plane that the direction of the wind had changed may have not been received by the pilot, causing him to fly up to fifty miles off course.
The Fate of Flight 19
The tale of Flight 19 started on December 5th, 1945. Five Avenger torpedo bombers lifted into the air from the Naval Air Station at Fort Lauderdale, Florida, at 2:10 in the afternoon. It was a routine practice mission and the flight was composed of all students except for the Commander, a Lt. Charles Taylor.
The mission called for Taylor and his group of 13 men to fly due east 56 miles to Hens and Chicken Shoals to conduct practice bombing runs. When they had completed that objective, the flight plan called for them to fly an additional 67 miles east, and then turn north for 73 miles and finally straight back to base, a distance of 120 miles. This course would take them on a triangular path over the sea.

About an hour and a half after the flight had left, Lt. Robert Cox at the base picked up a radio transmission from Taylor. Taylor indicated that his compasses were not working, but he believed himself to be somewhere over the Florida Keys (the Keys are a long chain of islands south of the Florida mainland). Cox urged him to fly north toward Miami; if Taylor was sure the flight was over the Keys.
Planes today have a number of ways that they can check their current position including listening to a set of GPS (Global Positioning Satellites) in orbit around the earth. It is almost impossible for a pilot to get lost if he has the right equipment and uses it properly. In 1945, though, planes flying over water had to depend on knowing their starting point, how long and fast they had flown, and in what direction. If a pilot made a mistake with any of these figures, he was lost. Over the ocean there were no landmarks to set him right.
Navigational Confusion
Apparently Taylor had become confused at some point in the flight. He was an experienced pilot, but hadn't spent a lot of time flying east toward the Bahamas which was where he was going on that day. For some reason Taylor apparently thought the flight had started out in the wrong direction and had headed south toward the Keys, instead of east. This thought was to color his decisions throughout the rest of the flight with deadly results.
 |
The more Taylor took his flight north to try to get out of the Keys, the further out to sea the Avengers actually traveled. As time went on, snatches of transmissions were picked up on the mainland indicating the other Flight 19 pilots were trying to get Taylor to change course. "If we would just fly west," one student told another, "we would get home." He was right
By 4:45 P.M. it was obvious to the people on the ground that Taylor was hopelessly lost. He was urged to turn control of the flight over to one of his students, but apparently he didn't. As it grew dark, communications deteriorated. From the few words that did get through it was apparent Taylor was still flying north and east, the wrong direction.
At 5:50 P.M. the ComGulf Sea Frontier Evaluation Center managed get a fix on Flight 19's weakening signals. It was apparently east of New Smyrna Beach, Florida. By then communications were so poor that this information could not be passed to the lost planes.
At 6:20 a Dumbo flying boat was dispatched to try and find Flight 19 and guide it back. Within the hour two more planes, Martin Mariners, joined the search. Hope was rapidly fading for Flight 19 by then. The weather was getting rough and the Avengers were very low on fuel.
Two Martin Mariners were supposed to rendezvous at the search zone. The second one, designated Training 49, never showed up, joining the 5 Avengers as "missing."
The last transmission from Flight 19 was heard at 7:04 P.M. Planes searched the area through the night and the next day. There was no sign of the Avengers.
Nor did the authorities really expect to find much. The Avengers, crashing when their fuel was exhausted, would have been sent to the bottom in seconds by the 50 foot waves of the storm. As one of Taylor's colleagues noted, "...they didn't call those planes 'Iron Birds' for nothing. They weighed 14,000 pounds empty. So when they ditched, they went down pretty fast."

What happened to the missing Martin Mariner? Well, the crew of the SS Gaines Mill observed an explosion over the water shortly after the Mariner had taken off. They headed toward the site and there they saw what looked like oil and airplane debris floating on the surface. None of it was recovered because of the bad weather, but there seems little doubt this was the remains of the Mariner. The plane had a reputation as being a "flying bomb" which would burst into flame from even a single, small spark. Speculation is that one of 22 men on board, unaware that the unpressurized cabin contained gas fumes, lit a cigarette, causing the explosion.
Missing Avengers become the Triangle's "Lost Squadron"
So how did this tragedy turn into a Bermuda Triangle mystery? The Navy's original investigation concluded the accident had been caused by Taylor's navigational confusion. According to those that knew him he was a good pilot, but often navigated "flying by the seat of his pants" and had gotten lost in the past. Taylor's mother refused to accept that and finally got the Navy to change the report to read that the disaster was for "causes or reasons unknown." This may have spared the woman's feelings, but blurred the actual facts.
The saga of Flight 19 is probably the most repeated story about the Bermuda Triangle. Vincent Gaddis put the tale into the same Argosy magazine article where he coined the term "Bermuda Triangle" in 1964 and thetwo have been connected ever since. The planes and their pilots even found their way into the science fiction film classic, Close Encounters of the Third Kind.
Where is Flight 19 now? Well, in 1991 five Avengers were found in 750 feet of water off the coast of Florida by the salvage ship Deep Sea. Examination of the plane's ID numbers, however, showed that they were not from Flight 19 (as many as 139 Avengers were thought to have gone into the water off the coast of Florida during the war). It seems the final resting place of the lost squadron and their crews is still a real Bermuda Triangle mystery.
