1969 Map of Vernalis

About this map

The San Joaquin River defines the agricultural and industrial landscape of this region at the intersection of San Joaquin and Stanislaus counties. This photorevised survey documents a complex water management infrastructure, where the California Aqueduct, Mendota Canal, and the Hetch Hetchy Aqueduct converge south of Vernalis. The map captures the footprint of the San Joaquin City (Site), marked with a Historical Monument, alongside the active local aviation at New Jerusalem Airport and the nearby New Jerusalem Sch. To the north, the Deuel Vocational Institution sits near the Western Pacific line, while the Vernalis Gas Field and Pacific Gas and Electric Field indicate the importance of energy extraction. This era shows a transition from traditional rail-dependent settlements like Cochrane and Ohm toward the large-scale irrigation projects that transformed the Central Valley.
