It's easy to forget that Park City was once a silver mining town with over 1,000 miles of tunnels. Slow down on the slopes, and have a good look around. Picturesque rusty remnants of what once was can be spotted all over the place.
The ruin above is called the 'Skier's Subway'. It gave skiers an alternative mode of transportation (old mine cars!) to get to the top of the mountain, when too many people were waiting at the cable car. Three miles through a damp tunnel took about an hour, if in fact everything 'worked'. Needless to say, it was not everybody's favorite experience.
The Skier's Subway finally closed in 1969, when faster and more reliable transportation became available. One of the cars can still be seen in the Park City Museum (a great place to visit).
