About this map

The San Joaquin River meanders sharply through the eastern half of this 1915 study, carving a complex network of bends and sloughs such as Reid Bridge Slough. This fluvial landscape contrasts with the rigid geometry of the railroads and land allotments to the west, where the Western Pacific and Southern Pacific corridors drive development. Small rural hubs like San Joaquin City and Vernalis anchor the river-and-rail economy, while the New Jerusalem School serves the surrounding ranching community. The map also delineates the extensive El Pescadero land grant, illustrating how older Spanish-era land patterns persisted alongside modern infrastructure. Subtle features like the Ohm siding and the Yarmouth station show the density of rail stops that supported Central Valley agriculture before the dominance of regional highways.
