Blown sands are one of very characteristic landscape elements of Olkhon Island on Baikal. The are characterized by anthropogenic genesis and occur against a background of both taiga and steppe. They most of all have originated in result of damaging of older dune forms. Material of these dunes is the effect of transformation of the Neogene lacustrine deposits and Baikal beach. Fields of contemporarily blown sand, especially of Peschanka, are shaped by north-western and north-eastern winds and the relief has highly deflation character. Blown sand are mainly medium-grained and in some places coarse-grained, they contain not many dusty particles. They are also characterized by low degree of mechanical abrasion.
