Abstract

Rock varnish, erosional grooves, and well-developed cavernous weathering phenomena occur in close association on a small biotite-monzogranite nunatak in the Northern Foothills region, Northern Victoria Land, Antarctica. The grooves, similar in appearance to the rinnenkarren described in the karst literature, are developed on steeply inclined bedrock surfaces while the rock varnish occurs on adjacent, more gently sloping bedrock surfaces. The preservation of both phenomena supports : the idea that landscape modification in this exceptionally cold and arid region of Antarctica is very slow, and the long-term stability of the Antarctic ice sheet
