Sedimentary Rock Layers on a Crater Floor
Sedimentary Rock Layers on a Crater Floor
ESP_040605_1575  Science Theme: Sedimentary/Layering Processes
This image covers layered sedimentary rocks on the floor of an impact crater north of Eberswalde Crater. There may have been a lake in this crater billions of years ago, and the area was once considered a landing spot for the Mars Science Laboratory.

There are diverse rock compositions, as we can see in an enhanced-color cutout. This image completes a stereo pair, so be sure to view the stereo anaglyph. Here is a sample at full resolution.
