o Layered Material Cut by a Valley Connected to East Jezero Crater

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

o Active Sand Abrasion in the Northern Polar Region of Mars

  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.
