Step back in time at the Argo Gold Mill and Tunnel, a testament to Colorado's gold rush era. Constructed at the mouth of the 4.2-mile-long Argo Tunnel, once known as the Newhouse Tunnel, this facility played a pivotal role in draining and servicing numerous mines between Idaho Springs and Central City. Built between 1893 and 1910, the Argo Tunnel facilitated the removal of ore and extended the productivity of the surrounding gold mines for decades. During its peak, the Argo Mill processed over $100 million in gold ore. The mill features state-of-the-art equipment from the Victorian Industrial Revolution, offering visitors a unique glimpse into the past. Explore the mill's structure, including gravity separators, amalgamation trays, and froth flotation cells, and discover mining artifacts in the indoor museum. Visitors can also try their luck at gold panning, a hands-on experience that allows them to learn the techniques used by early miners. The Argo Mill and Tunnel is not just a museum; it's an immersive journey into the heart of Colorado's gold rush history. Note that the Argo is part of a 400-square-mile EPA Superfund Site.
