DescriptionKeystone was established as a mining town soon after William Franklin and his daughter Cora discovered gold. Particularly lucrative was the Holy Terror Gold Mine, discovered in 1894. The owner named the Holy Terror after his wife, who was disgruntled that the family mines were never named in her honor. She took the joke in stride when it began yielding $70,000 worth of gold per week.
Keystone's rugged mining community was the inspiration for Stewart Edward White's 1901 novels “The Westerners” and “The Claim Jumpers.”
Two bridges lead to the top of Iron Mountain, which offers excellent views, including Mount Rushmore National Memorial. Three tunnels along 17-mile Iron Mountain Road form perfect frames for the four presidents' faces. The tunnels are 13 feet, 6 inches wide by 12 feet high.
