MARS RECONNAISSANCE ORBITER HIRISE IMAGES
September 28, 2011

o Layered Yardangs
  http://hirise.lpl.arizona.edu/ESP_022774_1865
  The aligned ridges are called yardangs, which are formed in areas
  where the dominant erosional force is the wind.

o Tithonium Chasma
  http://hirise.lpl.arizona.edu/ESP_023029_1755

  This complicated landscape of craters, slopes, and boulders is in
  an area called Tithonium Chasma, a large trough that is itself a
  part of the more well-known canyon system Valles Marineris.

o Gullies and Curved Ridges at the Base of Crater Walls
  http://hirise.lpl.arizona.edu/ESP_023328_1325

  These features likely formed during a period of high obliquity (tens
  of millions of years ago).

o A Network of Dust Devil Tracks
  http://hirise.lpl.arizona.edu/ESP_023734_1270

  The entire area in this image has been recently crossed by multiple
  dust devils.
