1956 Map of Tumey Hills

About this map

The high ridges of the Panoche Hills and Tumey Hills dominate this mid-century survey of the arid interior borderland between Fresno and San Benito counties. The landscape is defined by deep drainage networks such as Panoche Creek, Silver Creek, and Tumey Gulch, which cut through the uplifted terrain. An Approximate Boundary line runs diagonally across the topography, marking the transition between the two counties near the Griswold Hills. Evidence of resource exploration is present in the form of several scattered Oil Wells, a solitary Oil Well, and a Prospect located in the northern reaches near a Gaging Station. The infrastructure is sparse, consisting primarily of remote Jeep Trails and a Reservoir, reflecting the region's rugged isolation and focus on watershed and mineral management.
