MARS RECONNAISSANCE ORBITER HIRISE IMAGES
April 30, 2014

o Yardangs Forming Near Gordii Dorsum
  http://hirise.lpl.arizona.edu/ESP_035558_1830

  The purpose of this observation is to determine how these formations,
  called "yardangs" are forming within a layer of bedrock.

o The Active Dunes of Nili Patera
  http://hirise.lpl.arizona.edu/ESP_035603_1890

  By monitoring the sand dune changes, we can determine how winds vary
  seasonally and year-to-year.

o Changing Dunes and Ripples in Olympia Undae
  http://hirise.lpl.arizona.edu/ESP_036099_2615

  Because of the high latitude of the dunes, they are covered with water
  and carbon dioxide frost in the winter and are poorly illuminated.

o Sunken and Pitted Ejecta
  http://hirise.lpl.arizona.edu/ESP_036182_2230

  The ejecta visible in this image seems to be lower than the surrounding
  surface, which is unusual since ejecta is laid down on top of existing
  ground.
