1991 Map of Grapevine

About this map

Grapevine Canyon serves as a critical mountain passage where the southern Central Valley meets the rugged ascent toward the Tejon Pass. This 1991 survey captures the area's infrastructure-heavy landscape, dominated by the Governor Edmund G Brown California Aqueduct as it contours across the valley floor. The map highlights the intersection of transit and history at Grapevine, where modern services sit near the Rose Stage Station Historical Marker, a nod to the era of overland stage travel. To the north, the Tejon Oil Field and various borrow pits illustrate the region's industrial utility, while the southern portion of the map transitions into the protected wilderness of the Los Padres National Forest. The presence of Fort Tejon State Historic Park at the southern edge of the quadrangle marks the site of a 19th-century military outpost established to protect the pass.
