Abstract

Retreat of till-capped ice cliffs on Flanders Moraine, an ice-cored moraine, was measured at 35 transects over nine weeks of austral summer 1980-81. Retreat of clean ice slopes was four times faster than of debris-covered slopes. Slope evolution is postulated to vary with angle and depth of lakes at the foot of the slopes. Cliffs above deep lakes show parallel retreat due to block collapse whereas lower-angle slopes above shallow lakes decline. -from Author
