Boulders collect in a small depression in the middle of the central peak of Steno Q crater. Some of these boulders are as big as houses! Image width is 1.5 km, portion of NAC controlled mosaic, illumination from the southeast [NASA/GSFC/Arizona State University].
Portion of the northwest wall of Steno Q intersects with a slump block terrace. The steep wall (upper left) appears smooth but lineated (some of this linear pattern is traced in cyan). The relatively flat-lying terrace (bottom right) preserves more craters (outlined in yellow). Dotted lines indicate craters partially destroyed by the gradual creep of materials downslope.
