1952 Map of Vernalis

About this map

The San Joaquin River winds through the heart of this landscape, its meanders flanked by a network of levees and sloughs like Walthall Slough and Red Bridge Slough. The 1952 culture revision reveals an area defined by large-scale water management and infrastructure, from the Delta-Mendota Canal and Hetch Hetchy Aqueduct to the Deuel Vocational Institution in the north. This survey provides a window into a period of industrial agriculture and state-led development, where rail lines like the Southern Pacific and Western Pacific intersect at settlements such as Vernalis and Yarmouth. Local history is preserved in the location of the San Joaquin City (Site) and the New Jerusalem School, offering genealogists and researchers a precise look at the rural San Joaquin Valley before later 20th-century shifts.
