About
American fossil is giving you the opportunity of a lifetime. We have the only quarry in the world where you have the opportunity to keep every fossil you find. We have recently acquired the South Dempsey Quarry, in the Green River Formation and want to make it the most exciting destination in the world for families and everyone who loves fossils or the outdoors. Our quarry is open May 30-September 30th.

Loads of fun and rocks.
Sep 2021
American Fossil runs a fantastic operation. Visited the site on Sep 17, and had booked a 4hr slot. I was having so much fun cracking open rocks I ended up extending my time.
J'Nae, Gib and Sherie were amazing, free with good advice and knowledge they made the experience all the better.
Several families came and went while I was there and it was so much fun to hear the excitement in the kids voices as hey would find fossils.
A full day was fun, but ended up being a little long for me, by the end of the day I had lost my touch in splitting rocks and wasn't finding as much. All in all though I highly recommend American Fossil, not just for the fish, but truly for the entire experience.

An experience you don't want to miss
Sep 2021
Fantastic day digging fossils. I booked a full day and came away with so many great pieces. Extremely well run operation. Due to some personal time conflicts, I had to reschedule a couple times - Patrick Hogle was great to work with me on changing dates, recommending hotel & camp areas as well as other rockhounding areas to look at while I was in the area. Highly recommend this as an activity for the whole family, The staff was always available to offer tips on splitting, identifying your finds, and background of the geology of the area. Bonus was a line of cutting saws so you could properly trim the rock as needed.

Excellent Experience & Excellent Value
Sep 2021 • Solo
I'm not a paleontologist. I've never even been a good science student. But I have always had an interest in fossils and geology. And like most others I have an interest in getting the most bang for my discretionary dollars.

And American Fossils checked all those boxes for me. For truly far, far less than the cost of many other venues I had an opportunity to search for fossils, collect fossils, and at every turn staff were teaching me, encouraging me, and engaging my curiosity about all of it.

Val was particularly helpful in giving me a quick lesson on manipulating the rock to find fossils and helpful in cutting rock to save my find without taking too much heavy rock. He has a deep knowledge of the area and quarry history, to include explaining sediment layers and volcanic contribution to our geological surroundings.

The website recommended reading about the area, and suggested the book "History's Aquarium," authored by Seth Sorenson (Val's son). Your local library might have it for check out, but I purchased a copy on Amazon weeks before my American Fossils reservation. The book is a nice addition to my personal library and studying before digging really made the visit fun & informative. This is a good recommendation if you want to make the most of your visit. (Seth was there and autographed my copy.)

I'm going to make it a point to visit again!

And I'm still not a paleontologist, but perhaps I'm a little more aware of the science.

There really are fish fossils to be found.

Wonderful experience- found lots of fish fossil and the service was great. The drive on the unpaved road was better than average.

American Fossil trip
Sep 2021
We made the 14 hour trip to American fossil this past week to fulfill my childhood dream of finding vertebrate fossils and American fossil didn't disappoint. We did an 8 hour dig and went straight through; had it not been for the 75F weather with a nice breeze, it would have been miserable. Colder in the morning and hotter towards the end of the day. The staff were excellent and always ready to help or give information and answer any questions!. Tools, racks and saws were available for everyone. You can go at your own pace as well and you never feel "pushed". The area is small and you are restricted to what is provided- all of which keeps safety as the number one priority and helps focus on plenty of rock to explore. That, and finding fish! We found many intact fish and innumerable partials, as well as a small plant (a less common fossil), coprolites, scales, etc. which make for interesting conversation pieces! One very small concern was that it appeared we sifted through shale that was already worked over the day before by other patrons- not a big deal, as they opened a smaller section late in the day, whereupon we found many more fossils!!. We will be back with other family next year!

Amazing Trip - ready to do it again!
Sep 2021
This was such an awesome experience for my daughter and I! We did the four hour dig and found a whole bunch of fish fossils. The owners are super well organized and everyone that works there is very friendly and knowledgeable! We would not hesitate to go back again if we are in the area. Truly one of the best vacation experiences we've had.

One of the best family experiences as two educated adult professionals traveling and home schooling our kids.
Sep 2021
One of the best family trips and days we have spent blending science, adventure and sparking fire to the minds of our naturally curious 4 and 6 year old. Patrick, J'Nae and Gib were excellent. Patrick is the embodiment of a living PBS kids Wild Kratz character when it comes to all aspects of natural history, geology, paleontology and the biology of how and why we are in such a fossil rich site. His profound respect for the natural material and passion for teaching reflect his advanced background in education. The kids loved him. J'Nae and Gib made us feel so welcome and were more than generous with their time and experience in identifying our fossils and helping us get them ready for the long trip back to the East Cost. The fish and sting ray fossils we take home will be treasured as much as the staff that brought this experience to life.
