2015 Map of Grapevine

About this map

Grapevine marks the critical transition where the floor of the San Joaquin Valley meets the high elevations of the San Emigdio Mountains. This landscape is defined by the massive infrastructure of the Governor Edmund G Brown California Aqueduct, which skirts the northern foothills before the terrain rises sharply into the Los Padres National Forest. The geography here is a series of dramatic drainages including Grapevine Canyon, Metralla Canyon, and Reed Canyon that cut through the steep slopes leading toward Grapevine Peak. Local aviation and industry are represented by the Tejon Ag Airport and the Tejon Industrial Pkway Dr, illustrating the corridor's dual role as a high-altitude passage and an agricultural gateway. The map also traces the winding course of Grapevine Creek as it descends through the Castac Valley toward the northern plains.
