Now With Double the Limestones

With the addition of this Wyoming dolomite and seven other photos, I have just doubled the size and scope of the Limestone Gallery. I make these galleries, each photo with notes and information, because you can't learn about a rock from just one picture no matter how good it is. So come to the gallery and take it in. Put your new knowledge to use the next time you're out among the rocks.
