Crater Deformation

This crater is located at 37 N, a latitude far enough north that ground ice is present, possibly sculpting the terrain when it moves. In this image, the western rim of the crater has been deformed from its original, presumably circular, shape. Note, however, that lobes of material and radial grooves (seen best at full resolution) in the crater's ejecta blanket appear pristine in nature. Perhaps suggesting that ground ice moves the most readily on steep topography, such as on a crater rim.
