The San Andreas Fault cuts a definitive path through this section of the Diablo Range, shaping a complex landscape where the boundaries of Monterey, San Benito, and Fresno counties meet. The settlement of Priest Valley sits at a crossroads near Lewis Cr, surrounded by a series of high ridges and deep drainages including Mustang Ridge and Blue Canyon. For genealogists, the map identifies small burial sites like the Williams-Duckworth Cem and Clayton Cem, marking the presence of early ranching families in this remote interior. The terrain is characterized by a network of seasonal water sources such as Indian Spring, Log Cabin Spring, and Monroe Lake, which supported livestock across Peachtree Valley and Monroe Valley. The orientation of these valleys and the course of San Lorenzo Cr follow the dominant northwest-southeast structural grain of the California Coast Ranges.
