I then went to Lead, SD.
I learned there is the Sanford Underground Research Facility, they use the former Homestake gold mine (1868 to 2001).
They have a very nice visitor center in Lead.
This is where Raymond Davis installed a neutrino detector in the early 1960's, He won a Nobel prize in physics for his work.
The surface portion is 1/2 mile across and 1200' deep, the underground portion goes to 8000'
This is a compressed air powered locomotive
From there I went to the Crazy horse memorial, it was started in 1948.
Then to Mt Rushmore
