MARS RECONNAISSANCE ORBITER HIRISE IMAGES

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

  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.
