Gobi Desert from , and those of the ranges from higher, though in a few cases they reach altitudes of . The elevations do not form continuous chains, but make up a congeries of short ridges and groups rising from a common base and intersected by a labyrinth of ravines, gullies, glens and basins. But the tablelands, built up of the horizontal red deposits of the Han-gai (Obruchev's Gobi formation) which are characteristic of the southern parts of eastern Mongolia, are absent here or occur only in one locality, near the Shara-muren river. They are greatly intersected by gullies or dry watercourses.
Gobi bear Bears have very little genetic diversity, and is among the lowest ever observed in any species of Brown bear. Levels of genetic diversity similar to the Gobi Bear have only been reported in a small population of Brown bears in the Pyrenees Mountains on the border of Spain and France. Based on morphology, the Gobi brown bear has sometimes historically been classified as being of the same subspecies as the Tibetan blue bear. However, recent phylogenetic analysis has shown the Gobi bear to instead represent a relict population of the Himalayan brown bear. There are only 22 Gobi bears left
