MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Western Medusa Fossae Formation: Dust and Dunes
  http://hirise.lpl.arizona.edu/ESP_041864_1745

  The bluish sand in this image is thought to originate 
  from the bedrock that lies beneath the dust.

o Possible Sulfates in the Northeast Syrtis Major Region	
  http://hirise.lpl.arizona.edu/ESP_041893_1975

  This particular region has been studied intensely due to the 
  presence of volcanics from Syrtis Major and impact ejecta 
  from the Isidis Basin.

o Which Came First?	
  http://hirise.lpl.arizona.edu/ESP_042040_1275

  Let's untangle the history of certain formations in this image 
  of sand dunes trapped inside an unnamed crater in southern 
  Terra Cimmeria.

o Bizarre TARs

  Unlike other transverse aeolian ridges on Mars, these TARs have 
  blunt edges and serrated ridges. Why?
