# Tas-Kystabyt

The Tas-Kystabyt (Russian: Тас-Кыстабыт, Yakut: Таас Кыстаабыт) is a mountain range in the Sakha Republic and Magadan Oblast, Far Eastern Federal District, Russia. It is also known as "хребе́т Са́рычева" —Sarychev Range, in honor of 19th century Russian cartographer Admiral Gavril Sarychev.

## Geography

The Tas-Kystabyt rises in the southeasternmost sector of the Chersky Range System. The range is bound by the upper Indigirka River valley and its tributary, the Nera River. The highest mountain of the range is an unnamed 2,341 metres (7,680 ft) high summit.

The range stretches in a roughly NNW/SSE direction for about 175 kilometers (109 mi). It separates the Oymyakon Plateau to the west from the Nera Plateau to the northeast. To the east it is bound by the Upper Kolyma Highlands and to the south it overlaps with the Suntar Khayata Range.

## Flora

The lower slopes of the range are covered by sparse larch taiga. The higher elevations have only mountain tundra.
