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 cutout.
