MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Crater with Surrounding Bench in Sinus Meridiani

  The bench formed because these layered surface units are eroding 
  at a faster rate than the more resistant underlying materials 
  that comprise the rest of the crater.

o Light-Toned Layered Rock Outcrop in Ladon Valles

  These extensive layers may have resulted from ponding of water and 
  sediments that flowed into the basin from Ladon Vallis.

o Colorful Central Peak in an Unnamed Crater

  The colorful rocks exposed in the central peak visible in this image 
  probably reflect variations in mineral content that were caused by water 
  activity early in Mars' history.

o Spectacular Richardson Crater Dunes

  At the time of this image, the frost has likely disappeared to its 
  greatest extent and will begin to re-acummulate soon.
