Every year Skeleton Lake reveals a little more of her secrets. The lake remains frozen most of the year; however, during a brief warm period, the ice melts, leaving skeletal remains behind. An unpublished study based on research conducted on 5 skeletons found that the remains were 1,200 years old.
A new study, however, widened the research. DNA testing was performed on 38 skeletons. Researchers from India, the United States, and Germany, isolated three geographic regions of origins: 1. South Asian, 7th-10th centuries; 2. East Asian; and Mediterranean, both 17th-20th centuries. This supported the theory of several mass dumpings over 1,000 years. Moreover, none of the skeletons were related. This warrants more research.
