Dariganga

Dariganga 

a plain and hill region in the eastern Mongolian People’s Republic, in the Süchbaatar province. Gentle slopes and small hills are dominant in the region. Altitudes vary from 1,300 to 1,400 m. The greater part of Dariganga is covered with young basaltic lavas, in some places without soil cover, above which rise numerous cones of extinct volcanoes (for example, Ŝilijn Bogd Uul, 1,778 m; Bogd Uul 1,750 m; and Dzotol Chaan Uul, 1.373 m). At the bottoms of depressions there are salt marshes, takyrs, and small lakes. At the edges of the depressions there are accumulations of sand, of considerable size in the southwest (Mol cog Els). Old dry river valleys are characteristic of the region. There are desert and dry grass steppes. Groves of elms and willows grow along the lakes.
