[2] To the north and northeast rise the Putorana Mountains and to the east the border with the Syverma Plateau is not clearly defined.

To the west the Tunguska Plateau descends quite abruptly towards the Yenisei River valley and to the southeast rises the Angara Range.

The slopes of the mountains are often stepped and river valleys tend to form deep canyons in some areas.

[3] The highest point is a 962 metres (3,156 ft) high unnamed summit in the southern half of the northern part.

It is entirely covered by somewhat sparse and undersized larch taiga, except on the highest summits where only mountain tundra grows.
