MARS RECONNAISSANCE ORBITER HIRISE IMAGES
February 20, 2013

o Large Crater Northwest of Lomonosov Crater
  http://hirise.lpl.arizona.edu/ESP_025228_2550
  
  This observation was suggested by 7th and 8th graders at Evergreen
  Middle School, California, with a very good rationale for their target.

o Cones and Inflated Lava Flows
  http://hirise.lpl.arizona.edu/ESP_030192_2020

  A CTX image shows topographic cones in local depressions here. What are
  these and how did they form?

o Dark Deposits around a Volcanic Fissure Adjacent to Tharsis Tholus
  http://hirise.lpl.arizona.edu/ESP_030440_1945

  Based on small volcanic ash deposits on Mars, does that mean there has
  been recent volcanic eruptions there?

o Inverted Channels in Colorful Kasimov Crater
  http://hirise.lpl.arizona.edu/ESP_030609_1550

  These ridges are called "inverted channels" and mark the locations of
  ancient Martian river beds.
