Ulyxis Rupes is a large cliff, just visible in the image as indicated here by arrows. South is to the left, north is to the right. North-facing cliffs show layers of ice and dust, known as polar layered deposits (box 1). About halfway across the image, there are large ice deposits that are heavily covered (box 2). The overlying material has been blown into long dunes by the prevailing winds in this region.
With increasing distance from the south pole, the ice becomes confined to larger impact craters (box 3). Puzzling parallel structures in the martian dust can also be seen (boxes 4 and 5). Although the origin of these features is uncertain, it is possible that they are the result of underlying ice deposits.
