High in the mountains skeleton lake mystery

Why is the Indian Himalayan lake, 5 kilometers above sea level, full of human skeletons?
Since 1942, when one of the soldiers guard discovered infinite number of human skeletons floating in Roopkund the lake, it was an enigma until 2004.
Although people have visited the lake in the past, up to the moment dead human remains, from living eyes, hide the lake glacier. But every year it was melting and from permafrost the body residues were eventually discovered.
More than 60 years nobody has been able to identify who these people, from where they, and how they appeared in the lake.
The pathological riddle which researchers attempted to explain with the wide range of theories, but were able to reveal the truth only in 2004.

Since they were found during the Second World War, many believed that it is the dead bodies of the Japanese invaders.
But soon it was found that the corpse's body has at least 100 years old, and began to speculate about the 1841 in Himalayas the missing Kashmir army.
Numbers and the implicit times coinciding, so start guessing what could kill so many people.
There were different versions: an avalanche or landslide, another army attack or disease, even in a collective suicide.
However, as time has shown, none the perceived of reasons was not true. Moreover, not even close to the truth.
The seventh decade of the twentieth century, scientists decided to make research update.
This time, it was concluded that skeletons are 500-800 years old.
So this version about Kashmir Army has been strongly rejected and replaced by a new theory, that the lake has given to the world, the failure of the 14th century Sultan of Delhi troops bodies. Bone lesions testified that the dead have suffered some sort of accident, so the story again received a vague explanation and was forgotten.

Although for a long time nobody has been able to explain exactly what was the lake waves float losers and when and how they lost their lives.
In 2004, TV Channel National Geographic delegated to the skeleton lake a special research group. Their task was to solve a riddle, and about the Skeleton lake to make a documentary film. This time researchers' results were much more specific.
In particular, the DNA analysis of the remains revealed that 200 corpses group consisted of two camps. It has been a theoretical assumption that a group of pilgrims (most likely that it was some kind of a big family, attempted to move mountains) hired the current territory of Mongolia lived people that they are transferred to them through the Himalayas.
Second, it appears that skeletons are much older than was predicted before, their age - about 1,200 years ago.
Finally, National Geographic researchers managed to deny the landslide, suicide or murder hypotheses. Researchers have carefully studied what violations suffered Roopkund’s losers. Examination results testified that on the dead bodies are left many blunt object injuries - head, shoulder injury. However, other of the body parts was intact.
In addition, there are no pierced, sawn, trimmed wound characteristics.
So the battle hypothesis totally did not work.
It was found that people died from massive, round spherical objects.
And the answer was prompted by one of the legends of the local population.
The song tells the story of how a group of travelers trying to move mountains, but not demonstrated the proper respect to the goddess of Nandi or the mountains, and she killed them with a giant hail pieces and threw dead bodies into the lake.

According researchers from National Geographic, this "myth" have the truth - skeletons expert testified that 200 Roopkund’s lake bodies could have died from the massive hail ice pieces.
Unfortunately, the Lake District has not been properly excavated and protected, so the ice will continue melting every year, hundreds of tourists flock see this macabre scene, and many of them are tempted to pick up a memory of any bone or skull. Although researchers have investigated only 200 corpses, believed to be the lake (at the bottom of the ice, snow) to be at least 600 or more skeletons.
