Lakebeds in Holden Crater
Lakebeds in Holden Crater
ESP_011542_1530  Science Theme: Landscape Evolution
Holden Crater was once filled by at least *two* different lakes. The sediments deposited in those lakes are relatively light-toned where exposed, as we see in this observation.

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.

NB: North is to the left in the cutout image.
