Erosion of the Edge of the South Polar Layered Deposits

This oblique view of the sloping edge of the stack of icy layers over the South Pole has some interesting morphologies.

The slope appears to be eroding from a combination of landslides, block falls, and sublimation. The bright icy exposure in the larger landslide scar (upper right) suggests that this was a relatively recent event.

Small-scale textures over the scene are due to both blowing wind and the thermal expansion and contraction of shallow ice.
