This crater in Xanthe Terra is filled with material deposited by wind or water after the crater formed. The material later fractured into discrete flat blocks.

This fracturing may have occurred due to collapse over a subsurface cavity from where ground water evacuated, or under a sub-ice lake.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. (The original image scale is 53.0 centimeters [20.9 inches] per pixel [with 2 x 2 binning]; objects on the order of 159 centimeters [62.6 inches] across are resolved.) North is up.

The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado.
