This dark plains region is of a part of the Lavina Region in the southern hemisphere at 29.1 degrees south latitude and 337 degrees east longitude.  This image is of an area 45 kilometers (28 miles) wide and 77 kilometers (48 miles) long.   It shows a variety of features, including volcanic domes and pits, linear fractures, and high-standing mesas bounded by steep cliffs.   A bright streaky deposit at the base of the steep cliffs in the upper right indicates downslope movement of material, and possible erosion of accumulation of windblown debris.
