According to Professor Vitaly Larichev, of the Institute of Archaeology and Ethnography at the Siberian Branch of the Russian Academy of Sciences, the Sunduki site in Siberia is a 16,000 year old astronomical observatory. These statements are recorded in the Siberian Times article, "Is this the oldest astronomical observatory in the world dating back 16,000 years?."
According to my great-grandfather, James Churchward, the Great Uighur Empire (see map above) was the principal colony of the lost continent of Mu and was thousands of years old at it's height some 17,000 years ago. The fact that artifacts of such age have been discovered in the vicinity provides hope that evidence of the Great Uighur Empire has been found.
Of course, further study and research is necessary to show a link between the ancient Uighurs and the people that inhabited this area and many patiently await the confirmation.
Have a great day.
