MARS RECONNAISSANCE ORBITER HIRISE IMAGES
September 19, 2012

o Unusual Crater with Lava Flows Near Arsia Mons
  http://hirise.lpl.arizona.edu/ESP_017347_1585
 
  The origin of this structure is unclear but may be related
  to the breach in the crater rim to the left.

o A Small, Double-Ringed Crater
  http://hirise.lpl.arizona.edu/ESP_028162_2310

  The impact penetrated through the material and into the
  substrate and formed this "double crater" as it excavated
  material from these two layers of different strengths.

o Clay Color Inspiration
  http://hirise.lpl.arizona.edu/ESP_028367_2085

  The relatively bright areas reveal a complex terrain with a
  range of textures and enhanced colors.

o Cratered Cones in Grojt? Valles
  http://hirise.lpl.arizona.edu/ESP_028466_1955

  These cones are interpreted to be the product of explosive
  lava-water interactions, indicating that the region is covered
  by lava.
