Summaries are presented of (1) ground temperature data at 9 depths from 0.0-22.0 ft collected daily at Gulkana (Alaska) during 1952-1958, (2) comparative climatological data collected by the U. S. Weather Bureau of various periods of record, and (3) soil data from samples obtained in June 1946 and February 1955. Tables are given of (1) the mean or average climatological data, (2) the miximum, minimum, and average ground temperatures for the 7 years as determined from data recorded on the first day of each month, and (3) the ground temperatures recorded the first day of each month during the 1952-58 period. Ground-temperature gradients for a typical thaw and freeze season (1952-53) are graphed and the maximum and minimum temperatures recorded at each depth are also presented. Seasonal freezing varied slightly from year to year; the average seasonal depth of freeze was approximately 7.5 ft below the ground surface.
