MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Layered Material Cut by a Valley Connected to East Jezero Crater	
  http://hirise.lpl.arizona.edu/ESP_026359_1990

  This image shows layered bedrock composed of light- and 
  intermediate-toned materials.

o Active Sand Abrasion in the Northern Polar Region of Mars	
  http://hirise.lpl.arizona.edu/ESP_026839_2550

  The large dune field which surrounds Mars' North Polar cap is 
  actively being modified by the wind, with dunes moving at rates 
  of a meter or more per year.

o Streaks on the North Polar Layered Deposits

  These streaks may be formed by winds blowing bright water frost 
  over the surface, removing frost from the surface, or blowing dark 
  material over the frost.

o Pluvo Point

  Although we can clearly see the bright area in this image, it isn't 
  due to frost or ice at this time of year.
