About this map

The Temblor Range dominates the eastern horizon of this 1961 survey, where the border between San Luis Obispo and Kern County runs along the high ridges. Life in this semi-arid interior revolves around isolated water sources like Hughes Spring, Black Spring, and the curiously named Bellyache Spr. The landscape is a series of deep cuts through the terrain, including Holland Canyon and Wilkinson Canyon, which drain toward the broader San Juan Valley to the south.

Institutional and agricultural presence is sparse, centered on the Choice Valley Sch and the San Juan Ranch. A network of unimproved dirt roads and selected fence lines, meticulously noted by the Geological Survey, indicates a ranching economy dependent on the seasonal flow of San Juan Creek. The geography here is defined by high-elevation crossings like Palo Prieto Pass, which provided critical passage through the mountains before the development of modern highway systems.
