The Crystal Mill is a wooden powerhouse on a rock outcrop above the Crystal River at Crystal, in Gunnison County, Colorado. Despite its name it was not a mill but a powerhouse: river water drove a wheel that ran an air compressor, and the compressed air powered drills in nearby mines until 1917.

Seen June 2026: a Sopris Sun report on Treasure Mountain Ranch, which owns the land, describes the property as including “the historic Crystal Mill” and says the ranch hopes to hand the mill to a preservation nonprofit. A March 2026 Sopris Sun column puts its visitors at about 30,000 a year. Source Source Reported

💡 5 things to know
- Not a mill at allThe 1985 National Register nomination says the building has long been wrongly called a mill. It was a powerhouse: a turbine water wheel of over 90 horsepower ran a compressor, and the compressed air was piped to air drills in the mines. Source Source Source Checked
- 1892 or 1893?The National Register nomination, History Colorado and 5280 say it was built in 1892 (the nomination cites a December 1892 local newspaper). The Marble Tourism Association and the Aspen Historical Society say 1893. Source Source Source Source Source Conflicting
- A mill with many namesHistorically it was the Sheep Mountain Power House on the Lost Horse Millsite, also called the Sheep Mountain Tunnel Mill or Lost Horse Mill. The Marble Tourism Association says the name “Dead Horse Mill” was never historically used. Source Source Source Checked
- Power for the mines until 1917It powered the Sheep Mountain Mining and Tunnel Company’s workings and, per the nomination, the Inez, Bear Mountain and Black Queen mines, until mining stopped in 1917. Its machinery was later removed. Source Source Source Checked
- Private, fragile, much photographedTreasure Mountain Ranch has owned the mill since 1954, according to the nomination, and a new roof and cables were added in 1976 to keep it from leaning into the river. It is reportedly one of the most photographed sites in Colorado. Source Source Source Reported
