1961 Map of Shedd Canyon

About this map

Huerhuero Plains anchors this early 1960s study of central San Luis Obispo County, a landscape defined by expansive ranching operations and water-scarce terrain. The network of local commerce is visible through sites like Clarke Ranch, Jackson and Reinert Ranch, and Upton Ranch, which suggest a localized economy focused on livestock and dry-land farming. Deep canyons, including Shedd Canyon and Upton Canyon, dominate the topography, while numerous triangulation stations like VABM Almond 1711 and VABM Shedd 1616 indicate the importance of precise geodetic control in this complex drainage system.
