A GIS project was created in ArcGIS format. Alases are prominent representatives of cryogenic landforms, reflecting the history of the study area. They are the main feed for livestock in Central Yakutia. The purpose of the work is to identify the nature of the distribution of alas formations and make a spatial analysis of their distribution. In the study area, 4401 alas were digitized, spatial geographic analysis was carried out using GIS technologies. The results of spatial analysis are reflected in the form of maps. The quantitative charac-teristic of alas is given.
