Abundant dust devil tracks dominate the scene in this THEMIS visible image. The dark streaks across much of the surface are formed when dust devils sweep up the dust and reveal the darker underlying terrain. Notice how the dust devil tracks are continuous over changes in topography (e.g. crater rims) and how the lengths and thicknesses of the tracks vary. This indicates that the dust devils vary in their size and duration.
