o Light-Toned and Possible Hydrated Materials in Gullied Crater	
  http://hirise.lpl.arizona.edu/ESP_025472_1405

  This observation shows a gullied crater in the Southern mid-latitudes 
  with light-toned deposits near the center of its floor.

o Well-Preserved Impact Crater with Ridges	
  http://hirise.lpl.arizona.edu/ESP_025557_1705

  Although the rim of this well-preserved crater and its smooth walls 
  are very impressive, so is the spectacular collection of ridges draping 
  the floor.

o Northern Polar Dune Field	
  http://hirise.lpl.arizona.edu/ESP_027378_2540

  These dunes, known as barchan dunes, usually form where there is a 
  moderate supply of sand and a prevailing wind direction.

o Polar Cliffs and Falling Blocks	
  http://hirise.lpl.arizona.edu/ESP_027451_2635

  There is an ice sheet at the North Pole of Mars that is a few miles thick 
  at its center, and at some places it ends in steep cliffs.
