Blowin’ in the wind

Blowin’ in the wind
Blowin’ in the wind It was this Panoramic Camera (Pancam) image that led the MER scientists to command Opportunity to drive back uphill from station 2 in Perseverance Valley to an outcrop they named La Bajada. The whole answer might not be blowing in the wind now, but, said MER Principal Investigator Steve Squyres: “We’re pretty convinced that we are seeing little wind tails that are pointing uphill, little directional tails that show which way the [erosive] flow was going.” Look in the flat outcrop, in the upper portion of image, for the little nob-like features poking up with the tails of material following behind.
