ENVIRONMENT AND DISTRIBUTION THERMAL RELIEF FEATURES IN THE NORTHERN FOOTHILLS SECTION, ALASKA

摘要

This paper is concerned with the environment and distribution of thermal relief features - forms categorized in the existing literature as patterned ground, thermokarst, and various other features resulting from congeliturbation (Bryan, 1946, p. 640) processes. It seems war­ranted to include all these features in the same study since their distribution is controlled by the same environmental factors and they, in turn, provide the same implications regarding climatic and edaphic conditions.
