A chain of four saline lakes at the foot of the Gobi Altai, ranging from 1100m to 1235m in altitude. The lakes are shallow, with a saucer-shaped depth profile, and vary considerably in size both seasonally and from year to year. These lakes are known to be an important staging area for migratory waterfowl,
and it has been suggested that they might be a breeding area for the rare Relict Gull. The lakes provide grazing land for domestic livestock in an otherwise arid region.
