Abstract

Galena Creek rock glacier (GCRG), northwest Wyoming, exhibits most of the classic characteristics of rock glaciers. However, this view was challenged by Barsch, who asserted that the ice in GCRG is of permafrost origin. The AA. used new refraction seismic profiles on GCRG to determine the thickness of the debris mantle over ice. They cannot tell, on the basis of seismic data alone, whether the frozen material beneath the debris mantle is ice or a debris-ice mixture, but the results are not inconsistent with the glacigenic model for the origin of the ice
