Gelisols soils are geographically limited to high-latitude polar regions and localized areas at high mountain elevations.
Because of the extreme environment in which they are found, Gelisols support the lowest population percentage of any of the soil orders.
Gelisols are divided into three suborders: Histels, Turbels, and Orthels all of which are defined in other parts of this unit.2. From the U.S. Soil Taxonomy soil-order classification system.
