MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Possible Opaline Silica in the Central Uplift of Elorza Crater	
  http://hirise.lpl.arizona.edu/ESP_033722_1710

  The distinguishing feature of this central uplift is the various 
  types of bedrock that are observable at the surface.

o Eroding Terrain in Arabia Terra	
  http://hirise.lpl.arizona.edu/ESP_039113_1915

  At one time this was a flat smooth terrain, but over time it has 
  been eroded, most likely by the wind.

o Frosty Slopes in Late Spring	
  http://hirise.lpl.arizona.edu/ESP_039114_1115

  At this time of year only south-facing slopes retain the frost, 
  while the north-facing slopes have melted.

o Polar Layered Deposit Slopes	
  http://hirise.lpl.arizona.edu/ESP_039122_1080
 
  These deposits are quite extensive and partially surround the 
  South polar residual cap.
