MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Unusual Crater with Lava Flows Near Arsia Mons

  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

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

o Cratered Cones in Grojtá 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.
