The Mountain History Museum opened June 2010 in a restored county fire house in Lake Arrowhead. Under the direction of the Rim of the World Historical Society, the museum is open on weekends June through October annually. Serving multiple communities in the western San Bernardino Mountains, the exhibits and education programs keep alive the local history for residents and visitors to the scenic area. Although, in 2020, we remain closed due to the Covid 19 Virus.
The mission of the Rim of the World Historical Society is to promote, collect, and preserve a broad knowledge of mountain history essential to a basic quality of life in an increasingly diverse society.
