This etched terrain shows light-toned, angular depressions in southern Chryse Planitia in the area where Tiu Vallis empties into the Chryse basin. The etching process that removed the dark plains material may be the result of cavitation or plucking during active channel formation or wind deflation. Many small, volcano-like features occur in this region. The arrow points to one of these features, a low mound with a summit crater. The image is about 50 km across.
