"Fossil hunting is never a story of guaranteed success, but with the expert advice of the U-Dig crew, everyone is sure to find a 'bug' or two. I wish I knew about this place sooner, because I will definitely be back. "

"I highly recommend this quarry if you are into trilobites. My wife and I took a four-hour dig, and we found 57 perfect large trilobites and several mortality plates. That is not including the trilobites we broke trying to lighten our shale load(around another 50.) This was a great day, and we would love to do it again."

"We only spent two hours digging but found lots of great finds! Jared was super knowledgeable and helpful and helped clean up some of the finds to make them look amazing! Highly recommend them!"

"They taught us how to split the shale, how to identify the trilobites and how to tell if a chunk of rock might have some fossils in it! They then cut them for us on a stone saw and taught is how to polish them! Super awesome service and very friendly! Definitely suggest this to anyone who loves fossils"
