NASA Mars Reconnaissance Orbiter HiRISE Images – February 6, 2013

– Layers in a Crater in Nilosyrtis http://hirise.lpl.arizona.edu/ESP_025001_2255

These layers formed long after the impact event and are likely deposits of dust and ice.

– Frost Avalanches on Steep Scarps http://hirise.lpl.arizona.edu/ESP_025010_2650

While HiRISE has captured other frost avalanches before, they never cease to amaze since it demonstrates that there are indeed active processes on the Red Planet.

– Layering in Central Candor Chasma http://hirise.lpl.arizona.edu/ESP_025112_1750

A Context Camera (CTX) image of this area shows faulted layered deposits near the contact between the layered deposits and wall rock.

– Conical Hill on South Polar Layered Deposits http://hirise.lpl.arizona.edu/ESP_030196_0970

The hill appears layered and may be an erosional remnant, in which most of the region been eroded to a depth of at least the height of this hill.
