1903 Map of Mt. Pinos

About this map

The Frazier Borax Mine and the Antimony Mine anchor the industrial geography of this high-elevation landscape at the turn of the century. Situated where the San Joaquin Valley meets the rising terrain of the San Emigdio Hills, the map documents a network of canyons and meadows within the Los Padres National Forest. The topography is defined by the Cuyama River and Sespe Creek, which carve through the wilderness between Pine Mountain and Alamo Mountain. Sparse settlements and landmarks like Wheeler Springs, Neasons Flat, and Mutau Flat suggest the area's role as a rugged frontier for mining and early mountain habitation. This survey, completed by W.T. Turner and S.N. Stoner in 1901, captures the complex borderlands of four counties—Kern, Ventura, Santa Barbara, and San Luis Obispo—before the development of modern infrastructure.
