Keystone in the Past

Keystone, famous for its Mt. Rushmore, was home to Carrie Ingalls after her marriage to David Swanzey. Carrie went to Keystone in 1911 to work at the newspaper, and married David the following year. David is credited with naming Mt. Rushmore in the 1880s.

Mary lived here following Ma's death, and Laura visited here twice in the 1930s.
