The range lies just west of the boundary of the Eurasian and the North American tectonic plates.[1] The mountains were formed by folding, and represent an anticline.[2]

The Verkhoyansk Range was covered by glaciers during the Last Glacial Period and the mountains in the northern section, such as the Orulgan Range, display a typical Alpine relief.

There are coal, silver, lead, tin and zinc deposits in the mountains.

Geography

Rising from the shores of the Buor-Khaya Gulf in the north, it runs southwards spanning roughly 1000 km (600 mi.) across Yakutia, east of the Central Yakutian Lowland, and west of the Chersky Range, reaching the Lena Plateau to the south and the Yudoma-Maya Highlands to the southeast. It forms a vast arc between the Lena and Aldan rivers to the west and the Yana River to the east. Its highest point is an unnamed 2,409 metres (7,904 ft) high peak in the middle section of the range.

The Verkhoyansk Range has a higher southeastern prolongation, the Suntar-Khayata Range, that is occasionally considered as a separate range system. Thus the highest point of the range in a restricted geographical sense is an unnamed peak in the Orulgan Range.[3] The Skalisty Range (Rocky Range), highest point 2,017 metres (6,617 ft), and the Sette-Daban, highest point 2,012 metres (6,601 ft), are located at the SE end and were also considered separate ranges in classical geographic works. The two ranges were 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 the Skalisty and Sette-Daban mountain chains belong to the Verkhoyansk Mountain System. Bilibin and Bobin also explored for the first time the Yudoma-Maya Highlands, directly adjacent to Sette-Daban.[4]

Climate and flora

The world's lowest temperatures for inhabited places have been recorded in this region, and there is quite deep snow cover for most of the year.

The mountain range is home to an alpine tundra, supporting various species of mosses and lichens.[2] Some sparsely-wooded forests of mainly larch and dwarf Siberian pine are found on smooth slopes.[3]
