This terrain looks like lumpy sediment on top of patterned ground. The lumpy sediment is likely just loosely consolidated because it is covered with spidery channels .
This landform is uniquely Martian, formed in the spring as seasonal dry ice turns directly into gas that erodes channels in the surface.
This target was identified by citizen scientists at Planetfour: Terrains .
