Xinjiang is split by the Tian Shan mountain range ({{ug-textonly|تەڭرى تاغ}}, Tengri Tagh, Тәңри Тағ), which divides it into two large basins: the Dzungarian Basin in the north and the Tarim Basin in the south. A small V-shaped wedge between these two major basins, limited by the Tian Shan's main range in the south and the Borohoro Mountains in the north, is the basin of the Ili River, which flows into Kazakhstan's Lake Balkhash; an even smaller wedge farther north is the Emin Valley.
