1934 Map of West of Tejon Hills

About this map

Wheeler Ridge stands as the primary landmark in this survey of the southern San Joaquin Valley, where the terrain shifts from the valley floor toward the rising slopes of the Wheeler Ridge landform. The landscape is defined by early 1930s transportation and infrastructure, anchored by the Golden State Highway and the Maricopa Road junction. This era of aviation and utility development is clearly visible through the presence of an Airway Beacon, a Landing Field, and the Tejon Substation. The mapping also documents the intersection of major land surveys, specifically the meeting of the Mt Diablo Base and Meridian and the San Bernardino Base and Meridian. Natural drainages such as Tecuya Creek and Grapevine Creek cut through the alluvial fans, showing the seasonal water patterns that historically shaped the region's agricultural potential before modern irrigation expanded.
