The highlight of the trip today was the Mammoth Site. It was a big pit that the Mammoths fell into and drowned. As a result, there are tons of Mammoth bones here. They’ve preserved many of the bones in place and you can tour it. It was surreal. You felt like you were on a movie set and everything was made of plaster, but its still a working archeological site.

If you visit Mount Rushmore, you must also visit The Mammoth Site. The Mammoth Site is an active archaeological dig in a facility. You can see parts of several Wooly Mammoth fossils still in the ground, being dug up. When entering the exhibit, go clockwise. The signage was low, and my wife and I walked the wrong way through the exhibit. QR codes are at several stations explaining the dig and can be read or listened to on a cell phone (no additional charge). They do offer a military and veteran discount.

Calling all geeks and nerds! If you, like me, have (since Jurassic Park) wanted to visit an actual working archeological dig, then this is the place for you. So much information on this self guided tour - you can be in and out in maybe an hour and a half, or you can enjoy all of the books and crannies and hang out for three hours - your choice. Cute gift shop, too :) Highly recommend

This was our 2nd time visiting the Mammoth Site. We have learned something new each time. It was also a great surprise that the exhibit hall was remodeled with 2 new hands-on exhibits for kids to learn more about water flow and elevation! We will be coming back.

We enjoyed our stop at the site while traveling through SD. The QR code self paced information made it easy to spend as much time as preferred in each area. So many fascinating things to read, look at, and discover.

Fantastic and informative, nicely laid out, impressive bones. Watch the 10 min video first. Great to see the actual work going on too. Surreal giftshop experience: 3 staff doing a stuffed mammoth inventory...!

This was an amazing site. I was absolutely fascinated with the work they are doing here. My wife spoke with one of the volunteer paleontologists and she had been working on one little spot for the last eight years. They are carefully recovering a part of history with a long way to go. Many interesting exhibits and history of the eras of history and the animals who evolved through time. This would be a must-see for with natural science curiosity.

This is a great destination if you’re really into fossils and mammoths. My wife and I went and it’s really geared towards children. It would have been excellent if either of our kids were 8-12 years old. When we have grandchildren, we will definitely come back

We had a group of all adults and we still loved going. It was so informative and we loved the free guided tour provided through the QR codes. We really didn't know very much about mammoths prior to our visit and though the museum did a phenomenal job of explaining everything. We would certainly return should we ever go back to this area.

Very interesting. The building was constructed around the “dig” to protect all the “finds”. The bones of At least 61 mammoths were found here. Of course, you have to listen to a lot of inaccuracies as far as the theory of evolution. If you know your creation facts, then you will see how this fits in. Truly amazing to enjoy this inside activity on a 100+ degree day..
