1970 Map of Big Bear Lake

About this map

Big Bear Lake anchors this 1970 survey of the San Bernardino Mountains, showcasing a landscape defined by seasonal recreation and high-altitude settlements. The northern shoreline is densely developed around Metcalf Bay and Boulder Bay, while the surrounding slopes of the San Bernardino National Forest are dotted with numerous youth and organizational retreats, including Camp Osito Rancho and Camp Tahquitz. The map captures the infrastructure of mountain life, from the Big Bear High School to the remote Glen Martin School and the Angelus Oaks PO at Camp Angelus. In the southern reaches, the San Gorgonio Wilderness protects high peaks such as Bernardino Peak and Anderson Peak. This era reflects a period of established alpine tourism, where Snow Summit and a network of trails like the Siberia Trail provided access to the crests above the Santa Ana River.
