The 1892 powerhouse above the Crystal River in what is now the virtual ghost town (except for a handful of summer-only residents) of Crystal in Gunnison County, Colorado.
Often called the Crystal "mill," the building, atop a high outcropping, it used water power to create compressed air that drove an air compressor that in turn powered other machinery at nearby silver mines. This site is often photographed, but only by those driving (or taking tours in) sturdy four-wheel-drive vehicles that navigate the steep, precipitous, sharp-rock-filled, one-lane road up to Crystal from the town of Marble far below.
