The paper presents the preliminary results of geomorphologlcal investigations being carried out in 1977/78 on ice-free shores of Admiralty Bay, King George Island. Effects of intensive frost weathering and structures of frost segregation, such as stone polygons, sorted circles, small stone stripes, gelifluction lobes have been observed. Structures of frost segregation are infrequent and weakly developed. Much more frequent and better developed are gelifluction forms occurring as lobes of various size and shape. Some attention was also paid to slope profiles and slope processes. Almost all slopes show concave or convexo-concave profiles and are modelled by gravitative, gelifluction and washing processes.
