Abstract—The soil cover patterns in the subtaiga landscapes on the northern spurs of the Tsagan-Daban Ridge
in the Selenga Mountains have been studied. Gray-humus lithozems and bedrock outcrops are typical of the
steep south-facing slopes under herbaceous pine forests. Soddy iron-illuvial podburs are formed under forest
vegetation on gentle slopes of northern and western aspects with a thick mantle of loose colluvial deposits.
Dark-humus metamorphic soils occur on the slopes of western and northwestern aspects below 700 m a.s.l.
under secondary forb–grassy communities that replaced the initial herbaceous pine forests. Windblown hollows
(yardangs) are occupied by humus psammozems under steppe pine forests. The morphological and physico-
chemical characteristics of these soils are discussed in the paper.
