Through the Grapevine

THROUGH THE GRAPEVINE: Streams of Transit in Southern California’s Great Pass

The mountainous passage that separates the great population of Southern California from the rest of the state is a zone of transit, from one epic region to another. Located at the collision of the San Gabriel and Tehachapi Mountain Ranges, this steep and convoluted terrain lies between Castaic, the northern edge of the Los Angeles megalopolis, and the depopulated place known as Grapevine, at the southern end of the Central Valley. Layers of traffic, water, and energy move like a braided stream through the mountainous terrain, connecting here to there.
