Barun Xiaba'er

Barun Xiaba'er is a small lake in the grasslands south of Buir Nuur. Its Mongolian name means “western mud lake”, and its bed contains deposits of sodium sulphate. The surrounding country belongs to the eastern edge of the Mongolian steppe, where small lakes and depressions punctuate broad stretches of grassland. Farther north, Lake Buir receives the Khalkh River and supports a much larger expanse of freshwater marsh.
