About this map

The rugged drainage systems of the Diablo Range define this 1955 survey of eastern Santa Clara County, where North Fork Pacheco Creek and its tributaries converge at Pacheco Lake. The landscape is marked by historic land grants including San Luis Gonzaga and Ausaymas y San Felipe, reflecting the region's deep ranching heritage. Settlement is sparse, characterized by isolated outposts like Dowdy Ranch, O'Connor Ranch, and Shaeirn Ranch.

Modern infrastructure follows old pathways as Highway 152, also known as the Pacheco Pass Highway, winds through the canyon past Bell Station. High points like Pacheco Pk serve as critical navigation aids with an airway beacon, while the northern portion of the map covers the early boundaries of Henry W Coe State Park. Geologic landmarks such as Lovers Leap and Elephant Head stand as prominent features overlooking the creek beds below.
