o Light-Toned and Possible Hydrated Materials in Gullied Crater

  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

  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

  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

  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.

All of the HiRISE images are archived here:
