Inder Lake

Inder is a saline lake in the Caspian lowlands east of the Ural River. North of its basin rise the Inder hills, a landscape of gypsum, mineral springs and karst hollows. Beneath them lies a great salt dome, whose upper layers contain potassium salts and numerous boron-bearing minerals. Meltwater, rain and springs feed the shallow lake in a country otherwise dominated by dry steppe.
