[4] The Olyokma Nature Reserve is a protected area located on the northwestern side, partly within the neighboring Lena Plateau.

It was first surveyed in 1934 by geologist Yuri Bilibin (1901—1952) together with mining engineer Evgeny Bobin (1897—1941) in the course of an expedition sent by the government of the USSR.

Bilibin and Bobin made a thorough topographic survey of the mountainous region leading separate research parties.

[7][8][9] The highest point of the Aldan Highlands is Mount Ningam (Гора Нингам), a 2,287 metres (7,503 ft) high peak located in the southern part, rising above the basin of the Gonam River, a left tributary of the Uchur.

[1] The system of the Aldan Highlands comprises a number of subranges where mountains are generally of middle height and their relief usually smooth.
