This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the
contact between an area of light-toned rock and an expanse of darker-toned
materials on the floor of Coprates Chasma. Remnants -- bits and pieces --
of the light-toned material are scattered throughout the scene, indicating
that this material once covered everything in this area. Coprates is one
of several chasms that comprise the giant Valles Marineris trough system.
