adjacent Moma Range (highest point ) with the Moma-Selennyakh Depression running along their western side, are included in the Chersky mountain system. Other ranges of the system include the Irgichin Range, Inyalin Range, Volchan Range, Silen Range, Onel Range, Polyarny Range, Nendelgin Range, among others. Hydrography The Chersky System includes three main river basins: Yana River - covering the western and northwestern parts of the mountain system. It includes rivers Oldzho and Adycha with its tributaries Tuostakh and Charky. Indigirka River, covering the northeastern, central and southwestern parts of the system, with rivers Selennyakh, Moma and Nera among others. Kolyma River, covering the eastern, southeastern and southern parts of the system, with rivers Zyryanka, Rassokha, Omulyovka, Yasachnaya, Taskan, Debin and Byoryolyokh, among others. Some of the higher ranges with alpine relief have glaciers. There are roughly 350 glaciers in the system with a total area of . There are also small lakes in the swampy valleys of some rivers, as well as lakes of glacial origin, such as Emanda and Tabanda Tectonics The range lies on the boundary between the Eurasian and North American tectonic plates. The precise nature of the boundary between the North American and Eurasian tectonic plates in the area of the Chersky Range is still not fully understood and is the subject of ongoing research. By the 1980s, the Chersky Range was considered mostly a zone of continental rifting where the crust was spreading apart. However, the current view is that the Chersky Range is mostly an active suture zone, a continental convergent plate boundary, where compression is occurring as the two plates press against each other. There is thought to be a point in the Chersky Range where the extensional forces coming from the north change to the compressional forces noted throughout most of the range. The Chersky Range is also thought to include a geologic triple junction where the Ulakhan Fault intersects the suture zone. Whatever the exact nature of the regional tectonics, the Chersky Range is a seismically active zone. It connects in the north with the landward extension of the Laptev Sea Rift, itself a continental extension of the Mid-Arctic Gakkel Ridge. Climate The Chersky mountains, along with the neighboring Verkhoyansk Range, have a moderating effect on the climate of Siberia. The ridges obstruct west-moving air flows, decreasing the amount of snowfall in the plains to the west. See also Balagan-Tas Kigilyakh
