In the no man's land of Uttarakhand in northern India, 5029 meters above sea level, there is a skull Lake named roopkund, which has about 300-600 skeletons. The remoteness of roopkund can be seen from the fact that it takes people four days to get there
In 1942, a local Ranger discovered the lake. The results of radiocarbon isotope analysis show that the dead people lived in the 12th-15th century. According to the non-human damage marks on the skull, they are likely to die in a natural disaster, such as hail, landslide or storm
In 2004, a scientific research team from ng National Geographic organization came here. Through DNA testing, the teams showed that the skeletons could be divided into two parts: one is short; the other is tall, probably noble. The results also suggest that they may have lived longer, probably around the 9th century
