PIA02919: Bi-level Gullies
NASA's Mars Global Surveyor shows two suites of gullies within a single impact crater in the Terra Cimmeria region of Mars. Gully erosion has cut into the layered rock exposed on the crater wall.

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows two suites of gullies within a single impact crater in the Terra Cimmeria region. The gullies near the top of the image are located on the northern wall of the crater, while the lower suite resides on a lower bench in the crater's northern wall complex. Gully erosion has cut into the layered rock exposed on the crater wall. Water may have been involved in their formation.
