Throughout the park are reminders of the region's mining days, and along several trails you will see the ruins of miners/ cabins, mining equipment, and mine shafts and tunnels (which are dangerous and should not be entered). Just outside the visitor center is the historic Rhodes Cabin, which dates from the period 1920 to 1932, when Clarence Rhodes and his wife Beatrice were custodians of the property for the U.S. Forest Service. The cabin, constructed of Englemann spruce and white fir, was one of nine tourist cabins built in the 1920s, along with a log lodge, a dining room, a dance hall, and a swimming tank. This particular cabin was rented to tourists until 1933, and from then until 1936, it was used as the home of the national monument custodian and his family. It was then used for storage before being restored by the Park Service.
