Abstract : A follow-up study of Red Rock Ice Cliff was undertaken in summer 1965 to time-test findings of more comprehensive studies in 1955 and 1956. Work was limited to mapping the ice cliff face and a portion of the ice drainage basin above it and to studying the effects upon vegetation. A total ice loss of 500,000 cubic meters/year was calculated for the small 2.2-sq km ice drainage basin whose surface dropped 5 m in a decade. Five regions, totaling 6% of the 1 sq km mapped, dropped by 8 m or more. Ice loss from the ice cliff decreased from about 2% to less than 1% due largely to a 30% reduction in the area of exposed cliff. The overall position of the cliff remained unchanged. There was less difference in cliff face detail in the two July maps ten years apart than in the several maps over one season. (Author)
