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...

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.https://www.mdpi.com/2073-445X/9/10/384rock glacierpermafrostinventorynortheastern Yakutiaremote sensing |

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.
