Each year, Keystone—a small town of less than five-hundred permanent residents—sees millions of visitors from around the world pass through on their way to witness one of America’s prized national memorials: Mount Rushmore. However, the history of this little mountain town spans well before the carving of the four stone presidents.
As with many towns in the Black Hills, gold was the catalyst for Keystone. At the height of the Black Hills gold rush, miners discovered gold just east of present day Keystone along Battle Creek. More and more gold seekers began to try their luck along the creek and soon the town of Harney, located southeast of Keystone, was established.
