Drennen's Mill -- stamp mill and concentrator -- on the Colorado River, 1900-1950

Photograph of Drennen's Mill on the Colorado River, 1900-1950. The mining operation sits near the water's edge (not visible) on a rocky embankment. A wooden watertank with a ladder sits at the top of the embankment. Steam pours from a pipe near the base. A series of pulleys and belts transfer power from an engine within the wooden structure housing the stamp mill and concentrator. Two men stand near the furnace which provides heat to the pressurized water tanks nearby. Small wheels on valves at left control the pressure. A barrel and a wheelbarrow sit nearby.
