This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows layers exposed by erosion on a slope in the martian south polar region. Both polar caps on Mars are underlain by a complex stratigraphy of layered material; the Mars Polar Lander -- lost in December 1999 -- was designed to have provided some insight as to the nature and composition of the layers in the southern hemisphere.
