Slope Processes and Periglacial Landscape around a Crater Wall Close to the South Polar Cap on Mars （HiRISE image ESP_038903_1115, Taken on November 13, 2014）

A series of slope features, comprising valley-head alcoves, gullies, and debris cones, develop across layered sedimentary rocks and extend into polygonal patterned ground terrain at the crater floor （right margin).
The top surface of the crater （left margin） also displays polygonal patterned ground terrain indicative of the ice-rich mantle that prevails at high latitudes. These landscapes imply that ice-melt erosion originates at the alcoves, and that the resulting wet debris flow enhances gulley erosion and finally deposits on a debris cone at the foot of the slope. The light-colored debris cone is covered with seasonal CO2 ice. Gulick （2014） introduces this image on the HiRISE web site. The distance across the image is equivalent to about 5 km.
