1957 Map of Hernandez Valley

About this map

Mustang Ridge and the Griswold Hills define the complex topography of this mid-century survey, where the San Benito River carves through the central valley. Small-scale ranching and early petroleum interests mark the landscape, evidenced by the De Alvarez Ranch, Laguna Ranch, and a cluster of Oil Wells and Oil Tanks near Vallecitos. The southern portion of the map is dominated by the Peachtree Valley and the Airline Highway, which follows the base of the Lorenzo Sanchez Ridge. The map documents a sparsely populated rural frontier with isolated infrastructure like the Bitterwater Tully School and an Oil Pumping Station (Inactive) near the confluence of James Creek and the river. Notable for family-named landmarks and old ranch sites, the area remains focused on cattle and early resource extraction, with many locations accessible only by Jeep Trail.
