MARS RECONNAISSANCE ORBITER HIRISE IMAGES
February 11, 2015

o Gullies and Bedrock in Nirgal Vallis
  http://hirise.lpl.arizona.edu/ESP_020087_1515

  The gullies in this image are within the valley wall of an
  ancient channel, a testament to flowing water in Mars' ancient past.

o A Large, Longitudinal Dune
  http://hirise.lpl.arizona.edu/ESP_039568_1120

  Longitudinal dunes form when the wind switches between two common
  directions.

o Boulders in Gully Alcoves
  http://hirise.lpl.arizona.edu/ESP_039747_1090

  In the spring, when the ice warms up and transitions to gas,
  dislodging material on the slope and forming a gully.

o Fan-Shaped Deposits in Bigbee Crater

  The rim of Bigbee has been heavily modified from its original form,
  presumably by water and wind.
