The connotation of the term rock glacier, has been one of a common origin form but it is increasingly appar- ent that we are studying a range of landforms which, with the exception of the glacier debris system type, have no relation- ship with glaciers. The approach to rock glaciers as a unique form is re-evaluated in the light of the vast numbers which occur in the southwest Yukon. The implications are that they are the norm not the unusual in the development of the progla- cial landscape and that correctly identified will provide new evidence for post glaciation landscape evolution.
