1967 Map of Branch Mtn

About this map

The La Panza Range defines this high-elevation landscape within the Los Padres National Forest, where 1960s ranching operations and water management systems adapted to the arid California terrain. Water security is central to the map's layout, evidenced by the concentration of developed water sources like the Taylor Well, Water Tank, and numerous named springs such as Grizzly Spring and Dutchman Spring. These sites supported isolated holdings like the Carrisa Ranch, Buckhorn Ranch, and Yeary Ranch. Higher elevations are marked by the Branch Mtn summit, which served as a critical communications hub featuring a Lookout Tower and Radio Facility. The drainage network, including San Juan Creek and the Gypsum Canyon Fork, underscores the topographic isolation of these mountains before modernized road access altered the character of the southern San Luis Obispo back country.
