American Fossil Quarry
This private quarry near Kemmerer opens 52-million-year-old lakebed shale to anyone willing to swing a chisel, and on a good day fish come out by the dozen. Split as thin as you can: the fossils lie on bedding planes, and a careless whack destroys what a patient one would have revealed. Rarities have come out of this ground, and you keep what you find.
