"A different sedimentation of sorts, more hard clay in fossil as opopsed to the shale like layering at stonerose."

"The Fossil stuff splits nicely. Livy the boys and I got some nice plates from the area. First timers to the area generally get away with a bit more then those that have been there before. If you find anything of interest or value (historical or monitary) beyond just the normal leave fossils don't be expecting to keep it. They generally only allow you to take at most a half a dozen pieces that way others can enjoy digging and finding as well. The rare finds I believe they ask (tell) that you "donate" them to the Fossil dig.
I have not been to StoneRose as of yet but I am assuming they are pretty much the same.
The Clarkia fossil dig is interesting but by far not my favorite. The fossils are in a clay material that when it dries to fast it just falls apart into hundreds if not thousands of pieces ( I'm not one for large numbered piece jigsaw puzzles), and even when you dry it properly they are very fragile and still tend to break apart.
