Dark Materials on Olympus Mons
This image from NASA's Mars Reconnaissance Orbiter (MRO) shows blocks of layered terrain within the Olympus Mons aureole. The aureole is a giant apron of chaotic material around the volcano, perhaps formed by enormous landslides off the flanks of the giant volcano.
These blocks of layered material have been eroded by the wind into the scenic landscape we see here.
The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 28.3 centimeters (11.1 inches) per pixel (with 1 x 1 binning); objects on the order of 85 centimeters (33.5 inches) across are resolved.] North is up.
This is a stereo pair with ESP_013049_1980.
