Suor Uyata

The Suor Uyata (Суор-Уята; Суор Уйата) is a mountain range in the Sakha Republic, Far Eastern Federal District, Russia. The village of Andryushkino, a small inhabited locality of the Lower Kolyma District, is located 70 km to the SSE.

Kigilyakhs, rock formations that are an important element of the culture of the Yakuts, are found in the Suor Uyata range. 40 km to the ESE of the eastern end of the range, on the right bank of the Alazeya River, rises the 327 m high Kisilyakh-Tas, another important Kigilyakh site.

History
The Suor Uyata was first mapped in the summer of 1870 by geographer and ethnologist Baron Gerhard von Maydell (1835–1894) during his pioneering research of East Siberia.

Geography
The Suor Uyata rises in the northwestern area of the Kolyma Lowland, only 20 km to the east of the eastern end of the Ulakhan-Sis Range. It is a smaller range than the latter, of which it can be considered an eastern prolongation.

The main ridge stretches in a roughly WNW/ESE direction for about 60 km. Its highest summit is the 512 m high Salyr-Tas. To the north rises the Ulakhan-Tas (Улахан-Тас), a ridge that stretches roughly northwards for about 40 km, whose tallest peak is 576 m high.

The Suor Uyata is surrounded on all sides by marshy areas with slow-flowing rivers and a multitude of lakes. The sources of several rivers are on the range, including the Bolshaya Khomus-Yuryakh, Maly Khomus-Yuryakh, Kumuruk-Yuryakh, Soldat and Bya, as well as some source area tributaries of the Sundrun River on the western side.

Flora and fauna
The area of the Suor Uyata is marked by permafrost. The climate is subarctic and severe and the range is covered in mountain tundra.

The area of the Suor Uyata is part of the migration corridor of the Sundrun reindeer population, which includes the adjoining Ulakhan-Tas, the Kondakov Plateau to the NW, and the forest tundra of the Rossokha River basin. The Suor Uyata / Ulakhan Tas mountain zone is a protected area, a regional nature reserve.
