Gullies on Mars.

Image Size 300 DPI: 7 * 11 cm

Gullies eroded into the wall of a meteor impact crater in Noachis Terra. This high resolution view from the Mars Global Surveyor Mars Orbiter Camera (MOC) shows channels and associated aprons of debris that are interpreted to have formed by groundwater seepage, surface runoff, and debris flow. It is possible that these gullies indicate that liquid water is present within the martian subsurface today.
The MOC image was acquired on September 28, 1999. The scene covers an area approximately 3 kilometers (1.9 miles) wide by 6.7 km (4.1 mi) high.
