About this work
Holden Crater was once filled by at least two different lakes. The sediments deposited in those lakes are relatively light-toned where exposed, as seen in this observation from NASA's Mars Reconnaissance Orbiter. Each layer represents a different point in time and perhaps a changing environment for Martian life, if it existed. The elongated ridges with sharp crests are sand dunes. The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel.
