The passage of glacier ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the "stoss" (upstream) side of the rock and plucking on the "lee" (downstream) side. These erosional features are seen on scales of less than a metre to several hundred metres.〔Douglas Benn and David Evans, ''Glaciers & Glaciation,'' Arnold, London, 1st ed. 1998 ISBN 9780340584316〕 ==Etymology== The 18th-century Alpine explorer Horace-Bénédict de Saussure coined the term ''roches moutonnées'' in 1786. He saw in these rocks a resemblance to the wigs that were fashionable amongst French gentry in his era and which were smoothed over with mutton fat (hence ''moutonnée'') so as to keep the hair in place.〔 The French term is often incorrectly interpreted as meaning "sheep rock".〔Lutgens, Fred and Ed Tarbuck, ''Essentials of Geology,'' Prentice Hall, 2011, 11th ed.
