MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Troughs in Elysium Fossae
  http://hirise.lpl.arizona.edu/ESP_044884_2050

  The two linear depressions in this image form part of the Elysium Fossae 
  complex, a group of troughs located in the Elysium quadrangle of Mars.

o Possible Sulfate Deposits in West Melas Chasma
  http://hirise.lpl.arizona.edu/ESP_044892_1695
	
  In this region, hydrated sulfate salts have been detected, and are found 
  extensively throughout the Valles Marineris canyon system.

o Southern Winter Frost Accumulations
  http://hirise.lpl.arizona.edu/ESP_044909_1450

  With this image taken during mid-winter in the Southern hemisphere, we can 
  observe accumulating frost on pole-facing slopes.

o A One-Kilometer Crater on the Floor of Saheki Crater
  http://hirise.lpl.arizona.edu/ESP_044913_1580

  Much of the material has been eroded over time and has slumped downwards 
  towards the crater floor, leaving behind chalk-like streaks of color.
