The Chersky Range




The Chersky Range
The highest peak: Mount Victory
Height of the top: 3003 m

The Chersky Range is located in the North-East of Siberia, but it is not a ridge in the usual sense of the word, but is a mountain system stretched out over 1500 km. The highest point is Mount Victory, 3003 meters (according to outdated data 3147 meters). The Chersky Range is one of the last large geographical objects that appeared on the map of our country. It was discovered by SV Obruchev in 1926 and named for the researcher ID Chersky, who died during an expedition to Northeastern Siberia in 1892. The boundaries of the mountain system are the Yano-Oimyakonsk highlands in the south-west and the Momo-Selennyakh rift basin in the northeast. It extends through the territory of Yakutia and the Magadan Region.

The Chersky Range

In the western part of the mountain system, in the interfluve of Yana and Indigirki Hadaranya mountain ridges (up to 2185 m), Tas-Hayakhtakh (2356 m), Chemalginsky (2547 m), Kurundja (1919 m), Dogdo (2272 m), Chibagalahsky (2449 m), Borong (2681 m), Silyapsky (2703) M), etc. In the east, in the upper reaches Kolyma, The Ulakhan-Chistai Ranges (the highest point of Victory is 3147 m), Cherge (2332 m), etc. Often, the Miero-Selennyakh intermontane depression and the Selennyakh, Momsky and some other mountain ranges rising over it in the north also often refer to the Chersky ridge system . The Chersky Range formed during the Mesozoic folding, then gradually became peneplaned, and during the Alpine folding it split into separate blocks, some of which had risen (horsts) and others had fallen (grabens). Middle-mountain mountains prevail. Rises up to 2000-2500 m ridges (Ulahan-Chistai, Chibagalahsky and others) are distinguished by alpine relief and are carried by modern glaciers. The axial parts of the mountain system are composed of strongly dislocated and metamorphosed Paleozoic carbonate rocks, and the margins are composed of marine and continental strata of the Permian, Triassic and Jurassic periods (shales, sandstones and siltstones); In many places these rocks are broken by powerful intrusions of granitoids, with which gold, tin and other minerals are associated.

The Chersky Range

The climate is severe, sharply continental. In winter, a temperature inversion occurs when the temperature drops from the peaks of ridges (-34 ... -40 ° C) to depressions (-60 ° C). Summer is short and cool, with frequent frosts and snowfalls. The average July temperature rises from 3 ° C in the highlands to 13 ° C in some valleys. Precipitation from 300 to 700 mm per year (up to 75% of their amount falls in the summer). Permafrost is everywhere. Many rivers, including the Indigirka and its tributaries, cross the ridges in very narrow valleys; Mom and Selennia flow in the intermontane basins and have broad, sometimes marshy valleys. The rivers feed on the melting snow and summer rains. Over 60% of annual runoff is in summer, winter runoff is no more than 5% per annum. In winter, icing is frequent, and small rivers freeze to the bottom. Altitudinal zonality is represented by high-mountainous poplar-Chosenia forests on the bottom of river valleys, sparse larch forests in the lower part of the slopes of ridges and thickets of cedar elfin and alder, as well as stony, lichen and shrub tundra in the highlands. On the tops of the highest ridges are cold stony deserts.
