ROOPKUND locally known as skeleton Lake or Mysterious Lake , It’s lies in the Lap of Trishul  Massif , located in the Himalayas. It’s a high altitude glacial lake in the Uttarak hand  Roopkund is one of the important places for trekking in Chamoli District, Himalayas, near the base of two Himalayan peaks: Trisul (7,120 m) and Nanda Ghunti (6,310 m)  The Lake is flanked by a rock face named Junargali to the North and a peak named Chandania Kot to the East. Roopkund lake is covered with ice for most of the year Roopkund is known as a mystery lake and is surrounded by rock-strewn glaciers and snow-clad mountains. The lake is about two metres deep and invites hundreds of trekkers and pilgrims every year

IN 1942 A BRITISH FOREST guard in Roopkund, India made an alarming discovery. Some 16,000 feet above sea level, at the bottom of a small valley, was a frozen lake absolutely full of skeletons. That summer, the ice melting revealed even more skeletal remains, floating in the water and lying haphazardly around the lake’s edges.

Something horrible had happened here. The immediate assumption (it being war time) was that these were the remains of Japanese soldiers who had died of exposure while sneaking through India. The British government, terrified of a Japanese land invasion, sent a team of investigators to determine if this was true. However upon examination they realized these bones were not from Japanese soldiers—they weren’t fresh enough. As it turns out, all the bodies date to around 850 AD. DNA evidence indicates that there were two distinct groups of people, one a family or tribe of closely related individuals, and a second smaller, shorter group of locals, likely hired as porters and guides. Rings, spears, leather shoes, and bamboo staves were found, leading experts to believe that the group was comprised of pilgrims heading through the valley with the help of the locals.The researchers concluded that the death was due to a fatal blow on the back of their heads and not due to any wound by weapons, avalanche or landslide. The marks on their skulls and shoulders indicated at being hit by something round, like a cricket ball. The absence of injuries to other body parts indicated that hard round objects, possibly cricket ball sized hail stones or ice balls, fell from above.
