History

In 1829, German physicist Georg Adolf Erman during a round-the-world (1828-1830) journey reported the existence of "Seven Ranges" (Sette Daban) between 135° and 140° E in the area of one of the upper tributaries of the Yudoma.

The range was 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 Soviet Union. After conducting the first topographic survey of the area Bilibin established that this chain consists of three parallel ridges with pointed, often rocky peaks, and that it belongs to the Verkhoyansk Mountain System. Bilibin and Bobin also explored for the first time the Yudoma-Maya Highlands and the Skalisty Range, directly adjacent to Sette-Daban.
