Rising from the shores of the
Buor-Khaya Gulf in the north, it runs southwards spanning roughly 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. The Verkhoyansk Range has a higher southeastern prolongation than the
Suntar-Khayata Range, which 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. The
Ulakhan-Bom, highest point ,
Sette-Daban, highest point , and
Skalisty Range (Rocky Range), highest point , are located at the southern 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, located to the southeast of the Ulakhan-Bom/Sette-Daban/Skalisty ranges.

Hydrography The Verkhoyansk mountain system separates the basins of the
Lena River to the west and southwest and the
Omoloy and
Yana to the east and northeast. It is deeply cut by riverine
intermontane basins. Many right tributaries of the Lena flow westwards, having their sources in the range, including the
Kyundyudey,
Undyulyung,
Begidyan,
Sobolokh-Mayan,
Menkere,
Dzhardzhan,
Uel-Siktyakh,
Kuranakh-Siktyakh,
Byosyuke,
Tikyan,
Dyanyshka,
Lyapiske,
Belyanka,
Munni,
Kele,
Tukulan,
Tumara,
Nuora, and
Baray, among others. To the northeast flow left tributaries of the Omoloy such as the
Kuranakh-Yuryakh,
Arga-Yuryakh,
Bukhuruk, and
Sietinde. The
Tompo cuts across the range in its southern part, flowing from its source in the Suntar Khayata. The valley of the
Aldan is located to the south, where the river makes a wide bend. From the eastern slopes flow the rivers
Dulgalakh and
Sartang, which form the river
Yana further north, as well as its tributaries
Bytantay,
Nelgese,
Derbeke, and
Baky, among others. Rivers in the mountainous areas are usually frozen between September and May. ==Climate and flora==
