1919 Map of Sulphur Springs

About this map

San Joaquin River carves a deep path through the terrain depicted in this preliminary study, which was produced just before major hydroelectric and irrigation projects fundamentally altered the hydrology of the Central Valley. The map documents the historic transition from the nineteenth-century military and mining era to early twentieth-century settlement. It captures the proximity of Old Fort Miller and Old Millerton, the former Fresno County seat, along the southern bank. These sites, located near the Madera Co Fresno Co boundary, represent the foundational history of the region. Transportation at the time is anchored by the Friant and O'neals Road, which winds north toward Belleview. Because much of the northern sheet remains a Preliminary Edition Unsurveyed Area, the map highlights the rugged, unrefined state of the foothills during this period of transition.
