o Slope Streaks on a Dusty Planet

  The dark streaks on the slopes are locations where the dust has 
  slumped downhill revealing a less dusty surface underneath.

o On the Beauty of Yardangs

  The long, straight ridges form on Mars (and Earth) when the wind 
  strips away the inter-ridge material.

o Warm-Season Flows in Cold-Season Ravines

  Ravines (or very large gullies) are actively forming on Mars during 
  the coldest times of year, when carbon dioxide frost aids mass wasting.

o Darn Dust!

  While we had planned to take an image of sinuous ridges, dust clouds had 
  other things in mind.
