A piece of Mars: This is what dunes look like when they die. At least on Mars. On Earth they typically get buried or eroded away. On Mars geology works slowly enough that the steep slopes of dunes are gradually reworked and pitted, and covered in fine layers of bright dust. (HiRISE PSP_005980_1085)
