The range stretches from southwest to northeast for about 200 kilometres (120 mi), from the northern end of Lake Baikal to the sources of the Mamakan river, a left tributary of the Vitim.

The main ridge is relatively narrow, with sharp peaks, cirques and glacial troughs.

[2] The highest summit is a 2,641 metres (8,665 ft) high unnamed ultra prominent peak.

[3] The range forms a watershed that separates the Mama River basin to the north from the right tributaries of the Upper Angara to the south.

[4] The slopes of the range are mainly covered with larch taiga, with mountain tundra and bare summits (golets) at higher elevations.
