About this map

The San Andreas Rift Zone cuts a distinct northwest-to-southeast path across this portion of the Temblor Range, marking a geologically active boundary where the landscape is deeply scarred by tectonic movement. This 1961 survey, updated through the early 1990s, details a sparse ranching and watershed environment along the border of San Luis Obispo and Kern counties. Human activity is concentrated around Choice Valley, where the Choice Valley Sch and Bitterwater Road suggest a small, isolated rural community.

Water management in this arid terrain is evidenced by a network of named water sources such as Pear Tree Spring, Hughes Spring, and Bellpuche Spr. To the south, San Juan Creek and the San Juan Ranch anchor the local geography. The map provides a look at the drainage patterns of Holland Canyon and San Luis Canyon, illustrating how the steep topography of the Temblor Range dictates the placement of storage bins and seasonal corals.
