Mars dust devils
When dust devils pass over the surface of Mars, they leave dark, criss-crossing streaks on the land. They can cross over hills, run straight across dunes and ripples, and go through fields of house-sized boulders. The dust devils remove bright dust from the terrain, revealing a darker surface underneath.
The dust devils in the photos shown here were recorded by the Mars Exploration Rover Spirit in Gusev Crater on Apr. 15 and 18, 2005.
