o A Circular Crack

  The first thing anyone thinks of when they see circular features 
  on Mars is a crater. Is that the case here?

o Layers, Dunes and Cliffs in Hydrae Chasma

  Hydrae Chasma is a deep, circular depression that has steep walls 
  flanked by numerous landslides and a massive scarp along its southern 
  boundary.

o Monitoring a New Impact Site in Fortuna Fossae	
  http://hirise.lpl.arizona.edu/ESP_029583_1825

  This impact site is located on the floor of a large fracture within 
  Fortuna Fossae, formed sometime between September 2005 and May 2008.

o A Defrosting Mess

  Just like on the Earth, the frost layer that accumulates over the winter 
  will disappear as summer approaches and Mars heats up.
