Beneath the ice caps of both martian poles lies extensive deposits of layered material. Whether the material includes ice is unknown. In the north polar region, some of the layers contain dark sand, others may consist of dust cemented by ice. The south polar layers are a little bit more challenging to understand. In most places, they have been covered by thin mantles of debris that mask the true nature of the layered material. South polar layers were eroded to provide this spectacular view, but later the materials were almost uniformly covered with a material that has become cracked. This scene is located near 82.0
