Terby Crater

May 6, 2013
Terby Crater, sitting on the northern rim of Hellas Basin, has been filled by sedimentary deposits, perhaps deposited by or in water.

The northeast portion of these layers have been eroded by the wind, exposing the layers. The enhanced-color subimage is a sample of these materials, in which the different colors and textures represent different rock types.
