Inventory and Distribution of Rock Glaciers in Northeastern Yakutia
Rock glaciers are common forms of relief of the periglacial belt of many mountain structures in the world. They are potential sources of water in arid and semi-arid regions, and therefore their analysis is important in assessing water reserves. Mountain structures in the north-east of Yakutia have o...

Rock glaciers are common forms of relief of the periglacial belt of many mountain structures in the world. They are potential sources of water in arid and semi-arid regions, and therefore their analysis is important in assessing water reserves. Mountain structures in the north-east of Yakutia have optimal conditions for the formation of rock glaciers, but they have not yet been studied in this regard. In this article, for the first time, we present a detailed list of rock glaciers in this region. Based on geoinformation mapping using remote sensing data and field studies within the Chersky, Verkhoyansk, Momsky and Suntar-Khayata ranges, 4503 rock glaciers with a total area of 224.6 km2 were discovered. They are located within absolute altitudes, from 503 to 2496 m. Their average minimum altitude was at 1456 m above sea level, and the maximum at 1527 m. Most of these formations are located on the sides of the trough valleys, and form extended sloping types of rock glaciers. An assessment of the exposure of the slopes where the rock glaciers are located showed that most of the rock glaciers are facing north and south. |
