There are slightly higher tableland type elevations running across the plateau area, mostly in a roughly east to west direction.

[3] The Big Kuonamka, which forms the upper course of the Anabar River, has its source in the plateau and flows in a northeastern direction.

Rivers cut deep valleys or canyons, often flanked by scenic cliffs formed by very ancient eroded sediments.

River Kotuy cuts from the south across the western side and is joined by its tributary Kotuykan from the highest part of the Anabar Plateau.

[6] There are sparse forests of larch in the lower areas up to a height of 450 metres (1,480 ft) and mountain tundra with mosses and lichens in the higher altitudes.

[3] The climate prevailing in the Anabar Plateau is subarctic continental, characterized by a very low average rainfall of less than 250 millimetres (9.8 in) per year.
