1968 Map of Quien Sabe Valley

About this map

Quien Sabe Valley and the surrounding Santa Ana Mountains dominate this high-relief landscape in the late 1960s. The map illustrates a remote ranching economy centered around the Quien Sabe Ranch and Buena Vista Ranch, connected by a network of unimproved roads and specialized infrastructure like a remote Landing Strip. The topographic detail reveals the complex drainages of Quien Sabe Creek and Santa Ana Creek, which carve through the steep terrain of Schoolhouse Ridge and Little Quien Sabe Valley. Numerous isolated springs and water tanks are marked throughout the peaks, including Potrero Peak and Reinoso Peak, underscoring the importance of water management in these coastal ranges. The presence of a prominent Grant Boundary and the poetic Cañada de las Aguilas Reales reflects the area's deep-rooted land use history and heritage.
