In the summer of 2018 as a part of a complex landscape and geographical expedition researches of soils near the mountain river the Left Urbikan basin are conducted. The research is conducted in especially protected natural territory – Barguzin Reserve, in a remote part of Barguzin Ridge. During the field researches morphological descriptions of soils and landscapes of the studied territory were carried out. More than 50 samples of soils and vegetation are selected. The soil map of the explored territory made by the author on the basis of field descriptions by means of the Quantum-GIS program is presented in article. A soil cover of Barguzin Ridge rather various that is caused by strongly dismembered mountain relief and also other factors of soil formation. In structure of a soil cover altitudinal zonality is observed. Prevail such types of soils, as lithozems, petrozems, cespitose podzols, podsolic, gray, cespitose subdrills, alluvial humic, layered and alluvial humic and alluvial humic and gley soils. Satellite images are used for the mapping. Topographical materials allowed to consider a form and height of a surface (watersheds, slopes of a different exposition, etc.). The systematic list of soils of a river basin the Left Urbikan is made. Physiographic characteristic of the area of a research is given, consequences of the forest riding fire which happened on the explored territory in 2015 are given.
