Ala Shan

Ala Shan

 

(also Holan Shan, Chialan Shan), a mountain range in China, in eastern Kansu Province. The range stretches 270 km along the southeastern edge of the Ala Shan Desert, and along the left bank of the Hwang Ho (Yellow River). The slopes are steep and very rugged, with elevations to 2,855 m (3,600 m according to other data). The range is composed of Precambrian gneisses and Paleozoic limestones and schists. In the foothills are deserts; higher up are brush-covered mountain steppes with individual patches of meadow. There are islands of coniferous forests on slopes with northern and northwestern exposures.
