The Newhouse Tunnel was started in 1893 and completed in 1910. The tunnel ran from the east end of Idaho Springs to the northwest corner of Central City, a distance of 4.16 miles, and tapped some of the richest gold veins in the area. The Argo Gold Mill was built at the Idaho Springs end of the tunnel, and it recovered over one hundred million dollars of gold from the tunnel. The success of the Argo Tunnel lead to the digging of 43 additional tunnels around Idaho Springs, which helped keep the mines operating well into the twentieth century. In 1943 the Argo Tunnel flooded, killing four miners. It never re-opened, and the mill also ceased operations. The Argo Gold Mill was placed on the National Register of Historic Places in 1977.Rights management statement available at: http://library.mines.edu/digital/rights.htmlGold mines and miningScenes, undergroundUnderground miningStillImage
