Cryosols are widespread in the northern and central regions of western Siberia, from 73°30′ to 62° N latitude, where they formed under a vast spectrum of conditions, from tundra to taiga, including swampy areas (Figure 2.8.1). Between 62° and 60° N latitude, these soils occur only within the coldest ecotopes of forest areas.
