Dust Devils make dark, diffuse scribble markings on the Surface by kicking up Dust and are especially active in the Summertime over Dark Surfaces, such as those with many deposits of sand-sized material.

The Surface warms up in the Sunlight, creating the right conditions to form Dust Devils. Mars also has larger dust storms that can deposit a thin layer of Dust and eliminate the Dust Devil Tracks.
