  The ejecta blanket---remnants of the material from the original 
  impact--- is still visible indicating that the crater may be very fresh.

  This area also has a high abundance of hematite, a mineral that can 
  precipitate out of water.

  In the springtime the ice on the dunes in the North polar region 
  cracks, often in polygonal patterns.
