MARS RECONNAISSANCE ORBITER HIRISE IMAGES
January 25, 2012

o Double Layer Ejecta in an Arabia Region Crater
  http://hirise.lpl.arizona.edu/ESP_024872_2175

  After an impact, there sometimes multiple phases of material
  that fall to the ground, creating the appearance of layered-ejecta.

o Fluvial Fan on a Crater Floor
  http://hirise.lpl.arizona.edu/ESP_024887_2155

  This observation shows a terrific fan-shaped deposit, beginning
  where the channel enters a crater.

o Dune Composition

  Patterns of dune erosion and deposition provide insight into the
  sedimentary history of the surrounding terrain.

o Very Fresh Impact Crater Superposing a Wrinkle Ridge in Hesperia Planum
  http://hirise.lpl.arizona.edu/ESP_025237_1600

  Wrinkle ridges are long, winding topographic highs and are often
  characterized by a broad arch with superposed narrow asymmetric ridges.
