MARS RECONNAISSANCE ORBITER HIRISE IMAGES
October 5, 2011

o Crater with Surrounding Bench in Sinus Meridiani
  http://hirise.lpl.arizona.edu/ESP_023382_1845
  
  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
  http://hirise.lpl.arizona.edu/ESP_023383_1590

  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
  http://hirise.lpl.arizona.edu/ESP_023674_1590

  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.
