[3] The plateau has rich mining areas where iron and copper ores are extracted, as well as rock-salt, talc and mica.

Mountaintops are flat and elevations moderate; the highest point is the Namai,[4] a 1,464 meters (4,803 ft) high summit.

[5] This same mountain, however, is marked as a 4,852-foot-high (1,479 m) peak in the E-8 sheet of the Defense Mapping Agency Navigation charts.

The upper course of river Lena crosses the plateau roughly from south to north.

Its tributaries Kirenga, Ilga, Tutura, Tayura and Kuta join it in the plateau area.
