An "Icy" Crater on Mars

Mars has ground ice at high latitudes, and when new craters form there, they dig up the ice. Until this image, this had only been seen on the Northern plains, because the Southern highlands have less dusty surfaces and it is hard to find new craters there. This crater is on an outlier of the South Polar layered deposits, a thick stack of layers near the south pole made of ice and dust.
