Summaries are presented of 1 ground tempera ture data at 9 depths from 0.0-22.0 ft collected daily at Aniak Alaska during 1947-1958, 2 comparative climatological data collected by the U. S. Weather Bureau for the years 1944-58, and 3 soil data from samples obtained in August 1956 and July 1958. Tables are given of 1 the mean or average climatological data, 2 the maximum, minimum, and average ground temperatures for the 11 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 1947-58 period. Seasonal freezing varied slightly from year to year the average seasonal depth of freeze was approximately 3.5 ft below the ground surface. The data show that there is no permafrost at the temperature-well location to a depth of 22.5 ft.
