Geography
Yereymentau is one of the subranges of the Kazakh Upland system. It is composed by a number of ridges roughly aligned from north to south in the northern section of the range, and from southwest to northeast in the southern. The highest point is the 901 m high Akdym, located in the southern sector. Some of the main ridges of the Yereymentau are Altyntau —highest point 750 m— in the north, Zhartas —highest point 524 m— in the west, Karatau —highest point 661 m— in the east, as well as Bozachikirtau —highest point 658 m.

The mountains are of moderate height and have smooth slopes, as well as some rocky outcrops and cliffs in places. River Olenti flows at the feet of the eastern flank of the range. Some right tributaries of the Sileti originate on the western slopes of the Yereymentau and the Moiyldy, a tributary of the Ishim, has its sources at the southern end.
