///The ancient lake lines are distributed extensively at north foot of  Bayankala Mt., also the lake sediments and lacustrine topography. At present, 4 levels of lake terraces, multi-level of lake sediments and high level paleo-lacustrine sedimentation can be clearly observed around the shore of Zhaling Lake and Eling Lake. Exposed maximum altitude of lake sediments is 4615 meters, exceeding 328 meters of the modern Zhaling Lake and 346 meters of the Eling Lake. Multi-level lakeshore piled terraces or base terrace, lake sediments and high level paleo-lacustrine sediments distribute in the Zhaling Lake and Eling Lake valley basin. Multi-level pale-o-lacustrine sediments and high level paleo-lacustrine sedimentation whose altitudes are about 50 m to 350 m above modern Zhaling Lake and Eling Lake distribute locally at bedrock hills of Xiaoyemaling, Dayemalin, Zhaling Lake north and other areas. The forming age of the lacustrine sedimentation from ancient high level lake at the north foot of Bayankala Mt. could be middle Pleistocene epoch.
