Big Planet, Tiny Vehicles (http://www.astrobio.net/news/modules.php?op=modload&name=News&file=article&sid= 1312&mode=thread&order=0&thold=0) - great interview with Steve Squyres


[SPIRIT:]The big reason that we've been very slow going up the Hills is we keep finding good stuff. After sprinting across the plains, which had a fairly uniform deposit of compositionally identical blocks of basalt, all of a sudden we're in this incredibly target-rich environment in the Columbia Hills with layered rocks and clear evidence of aqueous alteration - water activity. It's fascinating stuff. It almost feels like when we were back at Eagle crater with Opportunity; it's like every rock brings some new revelation, and slowly the picture starts to fall into place.
...
[OPPORTUNITY:] Then we're going to head south. The most appealing target within reach is this so-called "etched terrain." It lies about two kilometers to the south of us, and we believe it is similar to the rock we've seen so far, but not exposed by impact. It was exposed by the gentle erosive action of wind. That's important, because anytime you have an impact, it's very disruptive. It's like throwing the rocks in a blender, and it really gets jumbled up. It's been hard for us to unravel the geology because the rocks that we've seen in Endurance and Eagle crater have all been busted up by impact.

The nice thing about the etched terrain is that if these same layers of sediments have been exposed by the gentle action of wind over millions of years, they will not be fragmented the way they are at the craters. I think we may be able to see more intact stratigraphy there, and a geologic record that's easier to read.

It looks like Opportunity has started the first part of it's drive out of the crater:

Moving again, I wonder what route they'll take out of the crater :o

Not that one, I bet....
