Mars - Mariner 9

Pits and depression features near the south pole of Mars

Mars
High-resolution Mariner 9 image showing an area of irregular pits and depressions near the south pole of Mars. The depressions have flat floors and smooth walls. Similar features are formed on Earth by the scouring action of wind. The largest terrestrial example of these deflation hollows, found in the desert of north central China, are still much smaller than those shown here. The frame is about 75 km from top to bottom and is centered at 74 S, 7 W. (Mariner 9, MTVS 4270-24)
