This image covers two overlapping impact craters, one approximately 4 kilometers in diameter and a second that is about 3 kilometers wide. The smaller crater has a sharply defined rim that interrupts the rim of the larger one, indicating that the smaller crater formed more recently.

Rocks of several different colors are exposed in this crater’s walls; they are undergoing erosion into finer-grained debris that travels downwards and accumulates in small fans on the crater floor. The rocks exposed on the eastern crater wall appear bluer in enhanced color than the redder rocks of the southern wall.

These craters are in the Terra Cimmeria region of Mars’ Southern Highlands, where they provide windows into the diverse compositions of the ancient bedrock.
