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)
