Some pretty complex driving by the look of it:

That is my take of it too: A hard, plate-like crust slipped down the incline during the recent past. Of course, it begs the question, why is there crust at that spot?

QUOTE (Chmee @ May 18 2005, 07:22 PM) That is my take of it too: A hard, plate-like crust slipped down the incline during the recent past. Of course, it begs the question, why is there crust at that spot? I wonder if Spirit caused a shifting of the outcrop when it drove up on the other side of Larry's Lookout on Sol 409, and drilled a rat hole on Sol 416? That slip looks extremely fresh. I 'm not sure how close this slip is to where Spirit was before, though. If the rock behind the "soil" was somehow pushed outwards, it could maybe cause the soil to break like that even if there wasn't a discrete crust- I think I've seen similar patterns when playing with damp sand on a beach. Very cool! |
