[2] The Kyundyulyun Range is located in northern Yakutia, about 400 kilometers (250 mi) north of the Arctic Circle.

[2] The highest point is an unnamed 640 metres (2,100 ft) high summit located in the southwestern part.

[2] River Buor-Yuryakh, the main left tributary of the Chondon, has its sources in the range.
