Soak up the woody goodness. |
I appreciate the link. While I see the sandstone layers, the thing up topside of the crater, while similar, doesn't seem quite the same.
More interestingly, I'm not a geologist, so what

these
Little Green Balls lying around all over the place?
They may not actually be green. My first thought would be sphericles created by the liquifying of the rock when the meteor struck. They'd form into sphericles, then harden before landing. My question would then be, "why are they all the same size?" Admittedly, rain drops are generally close to the same size, at least for any given rate of rainfall (the greater the rate in inches per hour, the larger the raindrops).
