Originally a part of Tayler’s series of five stamp mills, the waterwheel was moved as a community project to its present location in 1948. Since then, it has served as an important visual landmark for Idaho Springs residents and for those traveling through the area. In 1988, volunteers donated an estimated 3,800 hours of labor to the rehabilitation/restoration of what is considered to be a valuable community resource.

Soon after 1859, when Colorado’s first gold was struck in Idaho Springs, CO, the Argo and surrounding area became an international center of milling and tunneling innovation and served for many gold mines in Colorado. Partnerships between local entrepreneurs, highly skilled professionals, and international business leaders enabled projects of previously unforeseen scale, ambition, and productivity to be realized. The Mighty Argo has rekindled this spirit and will resume its role as a hub of activity and an engine of economic productivity for the region and beyond. The Argo Mill and Tunnel is a wonder of ingenuity, technology, and entrepreneurial spirit. Begun in 1893, the 4.2-mile-long Argo Tunnel cuts an ingenious path through the hills, draining and servicing hundreds of miles of workings, thereby prolonging the productivity of the famous gold mines in Colorado for decades. Many of the gold mines in Colorado would have become inoperable if not for the Mighty Argo.
