…and Dust-Devils

On a very light-toned and flat surface, a large number of dust devil tracks (See scheme: Emergence of dust devils) can be spotted on the left side of the image crisscrossing each other as dark streaks. Those marks are left behind when dust devils blow away the dust cover of the surface on their path. An oval hollow (hand of the angel) appears to be a large sublimation pit, maybe formed around a crater and allowing a view on the layered structure of polar deposits.
