This image shows a small landslide in Iani Chaos. Landslides are common on Mars where there are steep slopes, including this area where there are numerous mounds and hills.
What is unusual about this landslide is that it carved a path downslope as it moved, similar to a snow plow pushing away snow as it moves forward. This image is part of a stereo pair so that scientists will examine the landslide in 3D to understand its formation mechanism. [More at link]
