How would you interpret the semi-"layered look" on that rock that
Spirit bumped into today? Look carefully at the big rock here. It is
kind of layered.

By the way, The last series of pictures from Opportunity were quite
artistic I thought.

It must be tiring for the rover to go pushing through all that dust
though. Keep 'em going, folks. What a great mission!

I just got back a few weeks ago from Laos and Vietnam. Many of the
jewelers and curiousity dealers carried tektites. I bought a big
handful of them. Mostly nice dumbell and other aerodynamic shapes. I
got a nice layered one too.
