Olyokminsky District, and the eastern end of Irkutsk Oblast,
Bodaybinsky District. The plateau is bound by the

Tokko River, the largest tributary of the Chara, crosses the uplands from south to north. To the south rises the
Udokan Range of the
Stanovoy Highlands and to the north the
Lena Plateau. To the east rise the
Aldan Highlands and to the west the
Patom Highlands. The size of the plateau is roughly from north to south, and from east to west. The heights of the Olyokma-Chara Plateau are moderate, the average elevations are between and , although higher in the southern fringes. Mountains tend to be flat-topped, the highest point is
Murun, a high summit. The plateau is largely uninhabited. The settlement of
Torgo,
