This false color image shows sand dunes on the floor of Hale Crater. This 150 km x 125 km (93 miles x 77 miles) crater is located north of Argyre Planitia. Dark blue in this false color combination usually indicates basaltic sand. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image.
