The Crystal Mill, a beautiful relic of Colorado’s colorful mining past, has stood crazily on a rock outcrop above the Crystal River in the Elk mountains since 1893. But after withstanding more than a century of harsh winters in a rugged, remote setting near the ghost town of Crystal, its days may be numbered. Historic preservation efforts to save the structure through the intervention of a non-profit foundation are underway, but Crystal Mill Foundation president Heather Leigh said $10 million must be raised by next June to purchase it from the private family that owns it and secure its future, otherwise the owners are likely to sell it. “We really believe that making it a non-profit and putting it in a place where it is preserved and protected for the next century will help get it into the right place, and we have a very small window to do it,” Leigh said.
