Shenandoah--Dives Mill

The Shenandoah-Dives Mill or Mayflower Mill is an intact and functional but inactive historic ore mill 2 miles (3.2 km) east of Silverton, Colorado, United States. The mill was built in 1929 to recover gold, silver, lead, zinc, and copper from ore mined at the Mayflower mine and brought to the mill by an aerial tramway. Regularly active until 1945, it houses still-functional equipment for the separation by flotation of metals from crushed ores. It is the only intact and functional mill of its kind in Colorado. It was included in the expanded Silverton Historic District in 1997, and was declared a National Historic Landmark on its own in 2000. The mill is owned by the San Juan County Historic Society, which staffs an information and gift shop at the mill under the name Mayflower Mill. The mill is open for self-guided tours in the summer months.
