Description: Special Report
Abstract: The influence of surface cover on thaw penetration in alpine and arctic soils of Alaska was determined. Several manipulated treatments were employed: removal of all vegetation, mulching, shearing and fire. Thaw and subsidence more than doubled on the bare and sheared plots and increased up to 50% on the burned areas. Bulldozing of and traffic over ice-rich permafrost terrain resulted in considerable erosion and thaw.
