Very cool. That's a nice bit of rock, too, if you don't mind me saying. I'm going to guess... sedimentary, with clear iron deposits, possibly part of a river bed during the late Devonian-Mississippian— aaaaand I have no idea what I'm talking about. I would like to know more about geology so that I could describe such a rock. Alas, I cannot.
