About this map

Big Bear Lake anchors this survey of the high mountain terrain within the San Bernardino National Forest. The map documents a transition from the established shoreline settlements of Boulder Bay and Big Bear Lake town to the dense network of organizational camps and forest service outposts in the southern backcountry. Cultural landmarks of the era include the Bear Drive-in Theater and Radio Towers (KTOT), while the presence of Big Bear High Sch and Middle Sch marks the year-round growth of the community.

Further south, the landscape is defined by the Santa Ana River drainage and the San Gorgonio Wilderness. Here, the map reveals an extensive system of retreats such as Camp Osito Rancho, Camp Radford, and Camp Arbolado. High-altitude features like San Bernardino Peak and Shields Peak crown the southern edge, while historical routes like Clarks Grade and the Santa Ana River Road connect isolated locales like Seven Oaks and Camp Angelus.
