This image shows numerous dark streaks along a steep slope in the Acheron Fossae region of Mars.

This region is covered in thick layers of dust. On steep slopes, this dust occasionally becomes unstable and flows downhill, like small avalanches. The dark streaks are the scars left behind from these dust avalanches. The brighter dust is removed, revealing the darker rocks underneath.

The dust avalanches in this image are generally moving from the higher ground on the right side of the image toward the lower ground to the left.
