Fractured terrain and scalloped depressions
Just to the right of the brain textured crater, a pattern is faintly visible in the dark colored regions. This pattern originates from fracturing by thermal contraction, which created a polygonal patterned ground. Wind-blown dark dust is trapped in the cracks and responsible for the dark coloration of this region.
Scalloped depressions are omnipresent throughout the image. They have circular to elliptical shapes and their size varies between tens of meters to several kilometers and depth of several tens of meters. They are the result of ground ice melting or its sublimation, followed by collapse of the surface. The process of subsidence by ice loss in the subsurface is called Thermokarst. At closer look, the layering of the mantled deposits can also be seen in and around the scalloped depressions.
