The Mayflower Mill is one of the last fully intact mills in the Silverton, Colorado area. Also known as the Shenandoah-Dives Mill, it was the most advanced flotation mill of its time.
It has a long working history. Opened in the 1920s, it survived the Great Depression and WWII and finally closed in 1991.
This mill is fairly easy to get to. A graded dirt road leads to the site from the town of Silverton.
