Glaciers and Rock Glaciers
Click-on the graphic above to see full resolution. The four panels show my (J. Ellis) concept of how the Neoglacial glaciers and rock glaciers developed after the retreat of the Pleistocene valley glaciers. C = empty cirque M = non glacier-cored moraine TRGC = tongue-shaped rock glacier M-W = mass-wasting (headwall debris falling on remnant Pleistocene glacier ice preserved in cirques)
