I'm in Northern California (near Sacramento).
Those photos were taken by my father as he traveled from Kentucky to California in
the early-50's during his time in the Air Force.  I believe he stopped there for
the tour.  I saw these photos and I did a Google search on the mine
and found your page.  :-)
