Abstract
Work on the Fröya Gletscher, N.E. Greenland, appears to substantiate the evidence already brought forward for the irregular flow of glaciers over short periods. It appears possible to correlate the daily temperature regime with the flow of some “polar glaciers.” The distribution of thrust planes seems to have no noticeable effect on the flow. It is suggested thatBlock-Schollenmovement may underlie the jerky motion of some of even the slower moving glaciers. A subglacial stream bed on the Skille Gletscher was explored from the snout for a distance of 500 m. It is estimated that at the farthest point the ice was 76 m. thick. There appears to be good observational evidence for de Martonne’s theory of medial moraines extending to the bed of the glacier.
