Custer, SD, Day 1, June 27

Started out in relatively modern times--the last ice age, and 63 million years more recent then the dinosaurs. The Mammoth Site is an active archeological dig where they've already excavated more than ? Columbian mammoths and two wooly mammoths. They've preserved a lot of the fragile bones in place (they're mineralized, but not petrified), built a building over the entire site to protect it all and set up a walkway and guide so you can see what you're looking at. In addition to a lot of tusks, there are a couple almost complete skeletons!

Then to Wind Cave National Monument, where we had time for a short hike with beautiful views of the prairie before our cave tour. Very interesting formations. It's a dry cave, so instead of stalactites and stalagmites, it was popcorn and boxwork.

And more bison...
