Cover: Perspective view of a 5-km-wide, glacial-like lobe deposit sloping up into a box canyon along the crustal dichotomy boundary on Mars. The up-slope geometry of these deposits implies a past thickness of ice on the order of ~920 m at this location. Cessation of glacial conditions caused lowering of the debris-covered glacier surface to the configuration seen today. See “Late Amazonian glaciation at the dichotomy boundary on Mars: Evidence for glacial thickness maxima and multiple glacial phases,” by Dickson et al., p. 411–414.
