o Frosty Gullies on the Northern Plains

  Seasonal frost commonly forms at middle and high latitudes 
  on Mars, much like winter snow on Earth.

o Potential Active Processes in Porter Crater 	
  http://hirise.lpl.arizona.edu/ESP_040885_1295

  On the northern slopes are several smaller slope features that 
  have a morphology hinting at recurring slope lineae.

o Sedimentary Deposits within Ius Chasma

  Most of the larger chasmata contain kilometer-thick light-toned 
  layered deposits composed of sulfates, but it's a bit different 
  here in Ius Chasma.

o Purple Mountain's Majesty
  http://hirise.lpl.arizona.edu/ESP_041088_1535
 
  This small mountain is located near the northeastern rim of the 
   giant Hellas impact basin, and could be impact ejecta.
