Lake Buir

Lake Buir is a broad freshwater lake on the eastern Mongolian steppe. The Khalkh River enters through a delta of reeds, willows and wet grassland, while the Orshuun River flows out towards the north. Sand dunes and smaller lakes lie near its southern shore. The lake freezes from autumn into spring, and its waters and surrounding marshes support fish and large numbers of migrating birds, including swan geese and cranes.
