About this map

The Napa River valley and the surrounding hills of Sonoma and Napa counties appear here during a period of established viticulture and civic growth. The landscape is defined by its historic land grants, such as Carne Humana and Huichica, which still influenced the property lines and road layouts of the mid-20th century. Major institutional landmarks anchor the region, including the State Veterans Home near Yountville and the sprawling Napa State Hospital at Imola.

Transit and industry are centered on the Southern Pacific rail lines that connect towns like St Helena, Oakville, and Sonoma. The map captures the agricultural and residential character of the area before the era of intensive suburbanization, showing individual structures and localized landmarks such as the La Joya Mine and Napa Soda Springs. Educational and religious life is visible through numerous country schools like Enterprise School and the Mont La Salle School, while the Vallejo Home State Historical Monument marks the preservation of the region's early California heritage.
