The museum itself was not as impressive as we had hoped. But for $4 per person we were able to look at the enormous air compressor (the world's largest at the time of its use), look at a three dimensional glass map of the mine, walk through a dark tunnel with no lights so we could not see the exhibits inside, and look at other really old unlabeled equipment that had been used in the mine.
After poking around the nooks and crannies for a while, we decided to go back down to Gold Creek. Katherine had debated buying a pan to go panning for gold in the creek, but they were $8, and she doubted that she could recoup her investment by finding $8 worth of gold while we were there. Instead, she decided to pan for gold in the least efficient manner possible: scooping up mud, putting it in a depression on a rock, and pouring water over it by hand.
