MARS RECONNAISSANCE ORBITER HIRISE IMAGES
February 6, 2013

o Layers in a Crater in Nilosyrtis

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

o Frost Avalanches on Steep Scarps

  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.

o 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.

o 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.
