And this picture from Mars Reconnaissance Orbiter.
Described on the JPL Web Site as:
This image shows ground within the targeted landing area NASA’s Phoenix Mars Lander before the winter frost had entirely disappeared from the surface.
The bright ice in shallow crevices accentuates the area’s polygonal fracturing pattern. The polygons are a few meters (several feet) across.
The image is a small portion of an exposure taken in March 2008 by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.
