Paxson Luke, Alaska. In correlating these temperatures with snow cover, it was found that the burrow covered with the greatest depth of snow had a temperature range of from 32 to 21°F or 11 F degrees and an average for the winter of °F. The burrow with least snow covering, in which the bare ground could be noted during the winter, was occupied all winter. The thermistor was 30 cm beneath the surface of the ground, and the temperature here ranged from a high of °F to a low of °F or through.
