About this map

The Tehachapi Mountains and the southern edge of the San Joaquin Valley meet in this landscape defined by critical California water infrastructure. The Governor Edmund G Brown California Aqueduct snakes along the base of the foothills, a massive engineering feat that facilitates the transport of water across the state. This area serves as a gateway between the valley floor and the high country, with the Sierra Nevada and San Emigdio Mountains framing the surrounding terrain.

Water management dominates the valley's lower elevations through the 850 Canal and the Edmonston Pumping Plant Rd, while the steep ascent into the mountains is marked by numerous drainage systems like Pastoria Cr. Significant subterranean work is documented here, including the Carley V Porter Tunnel and a series of numbered tunnels such as Tunnel Number One and Tunnel Number Three, illustrating the complex logistical efforts required to navigate the Geghus Ridge and the Tehachapi Mountains.
