Brief introduction of Jishishan branch peak;
1, Dariga (Dari framework)
Located between Linxia, Xiahe and Xunhua counties, with an altitude of 4,636 meters, it is the highest mountain in Linxia and its vicinity, so it is called "Linxia Everest". Dariga Mountain was formed by the uplift of fault blocks, so although the altitude is high, the top of the mountain is gentle, and the elevation above 4000 meters is the first level of ancient leveling in Linxia area.
In the later stage, many depressions were formed in the planation plane under the action of glaciers. Later, the glaciers retreated, and the depressions accumulated water to form lakes. Dari Gacuo (4,250 meters above sea level, which means alpine lake in Tibetan, also known as Wushanchi) is one of them.
