Abstract

This paper reports field measurements of sediment depth around 2 whaleback landforms in order to investigate the relationship between glacigenic deposits and whaleback formation. The study site, at Lago Tranquilo in Chilean Patagonia, is situated within the Last Glacial Maximum (LGM) ice limits. Two facies occur on and around the whalebacks : angular gravel found only on the surface of the whalebacks, interpreted as bedrock fracturing, and sandy boulder-gravel in the sediment-filled depressions between the 2 whalebacks, interpreted as an ice-marginal deposit
