Theres an interesting picture here of a crater with a strange dark patch at one end, would anyone care to hazard an explanation? I thought it could be an exposed section of basalt, but I dont see why it wouldn't be covered with dust like the rest of the terrain.

Theres an interesting picture here of a crater with a strange dark patch at one end, would anyone care to hazard an explanation? I thought it could be an exposed section of basalt, but I dont see why it wouldn't be covered with dust like the rest of the terrain. Very cool. I'd speculate that the crater is actively sinking (especially the deeper section off center to the E (lower section in the image)). Could the dark deposits be mineral salts left behind by sublimating ice? -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
