In 1891, the Holden Lixiviation Mill sprawled over 22 acres at the edge of Aspen, boasting state-of-the-art technology and industrial design. Just 14 months after the new plant opened, Congress demonetized silver and the mill went bankrupt. Mike Marolt purchased the property for a dollar in 1940 as a family ranch. This site is unique. It tells the stories of both Aspen’s mining and ranching heritage.
