Layers in a Crater Wall
Layers in a Crater Wall
ESP_026061_1435  Science Theme: Landscape Evolution
This image is of the rim of a crater. The sun is low in the sky (only 15 degrees above the horizon) and shining full on this crater wall (you can see that the area beyond the rim has got long shadows).

The sun is beautifully illuminating a series of layers exposed in the crater wall which have a variety of different colors.

Note: the subimage is non map-projected, so approximate North is down.
