DISTIRBUTION AND CHARACTER OF PERMAFROST IN THE DISCONTINUOUS PERMAFROST ZONE OF ALASKA

In Alaska, the discontinuous permafrost zone includes that part of the permafrost region south of the Brooks Range. Variations in climate, geology, topography, and vegetation cause differences in the character and distribution of permafrost within this zone. On the basis of these differences, seven different types of permafrost areas are distinguished. These different types are grouped under two major categories: mountainous areas in which summits generally exceed 3,000 feet in altitude, and which are predominantly underlain by bedrock at or near the surface; and lowland and upland areas, in which summits generally predominantly underalin by thick unconsolidated deposits.
