Hi, guys!
Roopkund Lake or also known as Skeletons Lake is a high altitude lake in the Himalayas specifically Uttarakhand in India. Its name comes from the hundred of skeletons seen in the lake once the ice melts. It is a very shallow lake as well, at just about two metres. Now, it is a popular trekking spot, not only because of the skeletons in the lake but also because it's a very challenging climb for trekkers.
These skeletons in the lake were found in 1942 by Madhwal. But there were already reports about the skeletons as far back as the 19th Century. Aside from the skeletons, artefacts like jewelries and weaponries are also found on the area. When a group of archaeologists extracted the skeletons, they even found some with flesh attached to it still.
Some say the skeletons were the remains of King of Kanauj, Raja Jasdhaval and his pregnant wife, Rani Balampa. Along with them are their servants, a dance troupe and others. They are thought to have been trekking through a pilgrimage when the hail storm hit them.
Others believe that the skeletons belong to General Zorawar Singh of Kashmir and his army after they fought in the Tibet War of 1841. It is said that they trekked the area and got hit by the bad weather thereby causing them their death.
DNA studies of the skeletons revealed that about 70% of them were Iranians and the remaining were of Indian descent. It is now believed that the Iranians asked the help of the locals to find new land for them to settle in. It is also believed that cricket-sized hail balls hit them in their heads as they do have markings of such size. These skeletons are found to be about 1,200 years old already. These findings are done by the National Geographic Research Team.
I hope this helps!
