We took a ton of pictures so I'll let some of them tell our story of today. What you can't see though is how hot it was... 37C! We just wished we could stay longer in the caves where it was blessedly cool.
Sitting Bull Crystal Caverns
Exploring a small cave with flashlights
Going down, down many steps - about 300 feet underground to the main cave (going backwards was easier for adults on the steep steps!)
Dog-tooth spar crystal
Afterwards, we bought a bag of "dirt" so the kids could sift it and discover gems and crystals to take home (the kids loved this part and wanted to buy more bags of "dirt" to sift through!)
Mount Rushmore National Memorial
The proverbial "We were here" photo
A great talk by a park ranger explaining how Gutzon Borglum used his scale models to sculpt the four famous faces. What an amazing story of persistence (this is the 9th scale model version) and flexibility (to keep working within the limits of the rock)!
Big Thunder Gold Mine
Learning about the persistence of two miners who spent 30 years painfully digging this mine to find only 10 ounces of gold!
Panning for gold - it takes a bit of skill but we came home with a few flecks of gold - and it felt good to "play" in the water!
Tomorrow we're off to Sioux Falls, SD - basically just driving straight across the state!
