I'm particularly excited about the sulfate results...because so much of the material we are looking at is in sulfur rich caves where gypsum and other sulfate minerals play a huge role in the biology and the subsequent preservation of traces of that biology.

My overall fossil-hunting bias is heavily weighted to natural caves and fissures and overhangs,

On Earth, the bottoms of these cracks can house organisms in a much more pleasant environment than the surface at large. Obviously, if such communities thrive or thrived on Mars, some of the evidence may well be at the bottom of these cracks. We have much imaging evidence of these terrains on Mars for comparison to the similar terrains here on Earth, not just at the poles but many other high latitude and high altitude places.

Try handling different material... for different results.

I feel very excited. I'm looking forward to what they have to say. The most important thing is, is it right? Is it right for them, and is it right for me?

We are excited about being in the playoffs and the kids are looking forward to Tuesday.
