Description :
Recent field research and modeling experiments by the AA. suggest that Würm glaciation of Tian Shan Mountains had much larger extent than it was previously believed. Their reconstruction is based upon glacio-geomorphological evidence. Their data on past glaciation provide a solution for the so called paleogeographical puzzle of Lake Issyk-Kul. The Würm depression of regional snowline was found to be in the range of 1150-1400 m. A finite-element model was used to test two climate scenarios: with a gradual and with an abrupt change in snow-line elevation. It yielded ice-marginal positions which agreed with the field observations.
