The Hills in Ganges Chasma
NASA's Mars Reconnaissance Orbiter (MRO) observed this image of Ganges Chasma in the northeast portion of Valles Marineris, and opens into outflow channels that flowed to the north.
Scattered hills on the canyon floor may be remnants of chaos terrain that formed from collapse of the canyon. Some of the bedrock has diverse colors as we see in the enhanced-color (false color) cutout.
The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 53.5 centimeters (21.1 inches) per pixel (with 2 x 2 binning); objects on the order of 160 centimeters (62.0 inches) across are resolved.] North is up.
