MARS RECONNAISSANCE ORBITER HIRISE IMAGES
March 25, 2011

o Light-Toned Layering in Noctis Labyrinthus Pit
  http://hirise.lpl.arizona.edu/ESP_019377_1695

  Just like on Earth, rock layers can tell the geologic history of
  a region: it's a window to the past.

o The Beautiful Arc of a Dune
  http://hirise.lpl.arizona.edu/ESP_019992_1340

  In the full observation, we can see several dunes within a crater
  and a gorgeous dune that arcs to the center of the image.

o Spring Drama
  http://hirise.lpl.arizona.edu/ESP_021522_0930

  This region is also host to surface features with radially-organized
  channels carved in the surface by seasonal erosion by escaping carbon
  dioxide gas, known colloquially as "spiders."

o Possible New Gully Activity
  http://hirise.lpl.arizona.edu/ESP_021622_1095

  The dunes in this image, currently losing their winter coat of carbon
  dioxide frost, sport possibly active gullies on their southern edge.

o Dunes and Dust Devils
  http://hirise.lpl.arizona.edu/ESP_021641_1205
 
  In the Southern hemisphere we see fields of sand dunes on the floors
  of many craters.
