Pretty rock tease of the day: Yellowstone Ash Flow Jasper (Wyoming)

I sense a theme - it looks like you're only going to get pretty rock teasers in the form of unprocessed contact sheets for a while, but at least you can get an idea of what's coming up. This one is Yellowstone Ash Flow Jasper from Wyoming (USA), which was presumably formed by layers of volcanic ash. Apologies for lack of science content.

I have tinkered a little bit with one or two of these but most are raw off the microscope. Enjoy.

Pretty rock/fossil tease: Rainbow petrified wood (Arizona)

What rock do you pick when you can't decide on a colour? Rainbow petrified wood from Arizona, that's what. Photograph ALL the colours! This will need a spot of tinkering to bring out its best, but it's got great potential for animal prints, aurorae, and snow-clad forest. I love rocks. But you probably noticed that.
