While in South Dakota, we stopped by Hot Springs to see the Mammoth Site, the World's Largest Mammoth Research Facility.
They built walls around it and a roof to protect it from the elements.
We were given a guided tour through the areas then left to explore on our own.
You can be part of the dig, I think that'd be really cool but I'm afraid I'd miss something.
Here's the website if you want to plan your own trip there. :)
