Now yes - while it's fair to say we have arrived at the rim of Vic - the rule were that the 'arrival' date would be the sol at which the rover arrives at the point from which the mother-of-all-pans is taken... so we're not there yet. (i.e. We'll probably take photos when we arrive in Valencia on Sat PM - but personally, I wont feel I've arrived till the following morning when I have a look out the window....and you're right Fred - it's that FIRST big MOAP that is the important one )
But that doesn't mean we can't have a new thread Doug |

RE: Nix, Castor and Climber's comments--
I can't speak for every geo-type, but I'm not sure where we are in the stratigraphic section. One of the things we use to locate points in the section are marker beds. On Earth, we use chemical markers (such as the K-T iridium layer) or rock types (such as Cretaceous sands and Pottsville sandstones) or fossil markers. We haven't found (AFAIK) a good marker bed here. We did find some chemical differences in the evaporites at Endurance and we might find similar chemistries here, but we haven't seen a series of similar exposures along the traverse to tie things together. We have noted the Halfpipe Formation but we don't know if this is a distinct stratgraphic horizon of cobbles or discontinuous accumulations of cobbles. And we don't have accurate elevations on the traverse. The kids in the back room or the Suits in Ithaca may know more, but from what I've seen we haven't found that holy grail. What we can do is make some shrewd guesses and let them stand until disproved... --Bill -------------------- |
