This was such a fun activity! I went with some of my family and we did the half day dig. It was well worth our time… we found some amazing fossils! The staff were super helpful, knowledgeable and friendly. Definitely wear gloves, long pants and a hat. Bring plenty of water. This is an activity I would do again!

I had a recent private dig with these awesome folks. We found more fossils than we could carry lol. We found lots of fish and a croc tooth and croc "poop". Every member of the staff was professional, friendly and just fun to be around. Most of our day was spent with Keanu and he was so good with everyone in the family. I ended up having an unrelated health emergency and these folks were on it. They stayed by my side and kept me going until an ambulance picked me up. Many thanks to Doug and his wife for their care while waiting, I know it made a huge difference. These people are truly amazing and when I get my issues resolved I will be back!!!! Seriously, this place is THE place I will recommend!

We had a fantastic time at this extremely well-run and organized quarry! We are total beginners, a family of 4 with two 7 years old girls, who had a blast looking for fossils. The entire staff is incredibly friendly, knowledgeable, and helpful. We spent a full morning there of about 4 to 5 hours and our girls did not want to leave! They supply gloves, glasses, chisels, and hammers and expert instruction. Bring lots of water and sunscreen and prepare to get dusty! We especially appreciated the knowledge and help of Afton, one of the experts at the quarry, who patiently guided my girls and helped them open a huge rock to find 3 beautiful fish. It was the highlight of their trip! If you love fossils and are looking for a fun family activity this is the place! We are loaded down with beautiful fossils to take back to Houston, Texas!

We traveled to this place in early June and it was astonishing! The people were so kind and patient with us showing us how to split the rocks and what to look for! We learned quite a bit from them in just the short time we were there! Would love to revisit and hear some more jokes from the tiny foreman someday!!

Definitely worth the admission. We found a lot of high quality fish and even a partial croc tooth. The people running the quarry were extremely helpful and kind. We have done three trips to Kemmerer for fish fossils, including both public quarries, and this was easily the best experience we have had!

Had an amazing experience! Doug and Keanu were super attentive and knowledgeable. Half day was plenty to find some nice fossil fish. Brought gloves based on past reviews but didn’t use them… Would have rather brought knee pads or small stool, either way super doable without. Could see a bandana or face mask being 100% needed if windy.

Spent the last two days visiting this quarry. The first day we spent the full 8 hours. We learned a ton about the fish, turtles and other species found in the quarry. We enjoyed ourselves so much we came back for a second day. All the staff at the quarry were super knowledgeable and helpful! We came home with a ton of awesome fossils. We can’t wait for our next trip.

If you are in the area check them out but do NOT follow Google gps to get there. Use the directions from the website. Made the drive and my 3 and 1/2 year old and husband had fun smashing the rock to find fossils. Definitely want to layer up as it was quite windy when we went.

A life long dream come true at the age of 59. I am still so delighted over getting to do this.While this review might have some whining in it. I absolutely do not regret coming here and highly recommend it. But there is a learning curve. So please learn from our mistakes.1 negative that is not this places' fault.DO NOT FOLLOW YOUR GPS without really checking into it first. We were coming from Afton WY and our GPS had us turn on to the most awful washed out dirt road I have ever been on in my life. I think it was about 7 miles later we encounter a closed gate with a sign telling us no access to the quarry and it had directions on how to get to the quarry from Kemmerer. Yikes! LOL so we risked our vehicle back down that horrible road to get back on the hwy. Thank goodness we did not damage our vehicle. Sadly that debacle with that GPS misdirection lost us a hour that was planned for digging. :'(You really want to head there from Kemmerer.The quarry is a long ways down a well maintained dirt road. We checked in, were provided with gloves, a chisel and a hammer. We were given a quick instruction on how to split the rock and find fossils. We were directed to lines of rocks laid out and asked to stay away from the quarry walls and set free to find what we could find. At this point it really is just down to luck.We made it there with only 3 hours before they closed. But with the heat and sun I don't think we could of done 4 hours. It was in the afternoon.I was so worn out. I still had not gotten my perfect fossil. I told myself that the rock I grabbed was going to have to be the last one for the day. Bingo, perfect negative and positive fish!!Then we brought our discoveries to be cut down and reloaded our stuff.I do regret that was that I was so wore out. As there were plenty of fossils we found that we were just too dang tired to haul over and load up. I now really wish we would have suffered thru loading them up. Because I wish I had them. Especially when you see how much rock shops sell these things for. Lessons learned.We ended up so sore from lifting rocks and hammering that we did not even go to the other quarry the next day as we had originally planned to do.When we retire, this place is most definitely on our list of places to come back to!!But next time I am going to be sure we are taking the correct route. Will be going in the morning or when it will be under 80 degrees and has a breeze. And take pain killers before starting our hammering away.WELL WORTH EVERYTHING INVOLVED
This place is awesome. For starters the manager George was really great! He was extremely patient and helpful. My three year old bothered him most of the morning and he was fantastic. He answered all of our questions and made sure that we had an all around excellent experience. We found a tons of fossils. My one suggestion to people would be to go for 4 hours or longer. Any less time than that and you aren’t doing yourself or this place justice. We will be doing a larger family trip next year.
