IR Windstreaks

Windstreaks are features caused by the interaction of wind and topographic landforms. The raised rims and bowls of impact craters causes a complex interaction such that the wind vortex in the lee of the crater can both scour away the surface dust and deposit it back in the center of the lee. If you look closely, you will see evidence of this in a darker rim enclosing a brighter interior. This infrared image shows windstreaks in the region between Gordii Dorsum and Amazonis Mensa.
