At first glance, this lake appears to be a lake of horrors, something grotesque like the dead body-infested monstrous lake in Harry Potter. The Roopkund Lake does indeed look like something straight from a folklore horror. Located in a snowy valley at the lap of Himalayas, the lake is chock-full of skeletons! There were some theories floating around as to the identity of the 600-800 skeletons that were found there. According to the BBC, one theory assumes this was a cemetery where victims of an epidemic were buried. Another explanation proposes that several of the skeletons belong to Indian troops who took part in an unsuccessful military campaign into Tibet in 1841. After suffering defeat, over 70 soldiers were reportedly compelled to retreat across the treacherous Himalayan terrain. Unable to withstand the extreme weather, high altitudes, and harsh conditions during the journey back, they are believed to have perished along the route.However, a 2019 study claimed that these were the remains of Mediterranean migrants, some of the remains were dated as far as 1200 years. Researchers discovered that the individuals whose remains were found were not only genetically distinct from one another, but also lived and died across a span of nearly a thousand years. Even more remarkably, genetic analysis revealed that the deceased belonged to different ancestral groups. One cluster shared genetic characteristics with modern populations from South Asia, while another showed close genetic links to present-day Europeans, especially people from the Greek island of Crete. These findings challenged earlier assumptions, demonstrating that the deaths did not result from a single disaster or one tragic event, but instead occurred during multiple periods over many centuries.The lake is located in the Chamoli District of Uttarakhand.
