MARS RECONNAISSANCE ORBITER HIRISE IMAGES
November 20, 2013

o A Textured Mesa
  http://hirise.lpl.arizona.edu/ESP_033564_1405

  Also imaged by MRO's Context Camera, this observation shows one of 
  two odd, rounded mesas with a knobby/pitted texture.

o Martian Intersection

  This image depicts an intersection of several fractures on the floor 
  of Echus Chasma.

o Nirgal Vallis Tributaries	
  http://hirise.lpl.arizona.edu/ESP_033814_1525

  Although Nirgal Vallis formed long ago, likely by flowing water over 
  long periods, abundant wind-blown sediments transformed into dune fields 
  that now line the valley floors.

o Hydrated Sulfate Landslides in Ophir Chasma

 These different toned surfaces also mark a transition from one sulfate 
 mineralogy to another and variations in surface evolution.
