- 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.

Information about the Mars Reconnaissance Orbiter is online at http://www.nasa.gov/mro. The mission is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, for the NASA Science Mission Directorate, Washington, D.C. Lockheed Martin Space Systems, of Denver, is the prime contractor and built the spacecraft. HiRISE is operated by the University of Arizona. Ball Aerospace and Technologies Corp., of Boulder, Colo., built the HiRISE instrument.
