Steep-walled depressions on the floors of craters.



Mars: depressions on the floor units of impact craters (Fig. 1). Depression walls often have straight segments and exhibit layering. The parent craters tend to be shallower than the surrounding (i.e., ‘notdepressed’) craters (Korteniemi et al. 2005, 2006).
