About this map

Vineyard names like Zinfandel and St. Helena already define the upper valley in this late nineteenth-century landscape, while the lower reaches focus on heavy maritime and institutional infrastructure. The Mare Island Navy Yard stands prominently at the entrance to the Carquinez Strait, anchoring a waterfront that includes the industrial nodes of South Vallejo, Benicia, and Port Costa. To the north, the agricultural and social fabric of the region is evident in the Veterans Home near Yountville and the Insane Asylum south of Napa.

Transitioning from the marshy reaches of Grizzly Island and Suisun Bay to the rising elevations of St. John Mt. and Atlas Pk., the map reveals a complex system of land grants and rancho boundaries. Features such as Rincon de los Carneros and Huichica persist alongside the growing rail corridors of the Southern Pacific R.R. and Northwestern Pacific R.R.. Local destinations like Napa Soda Springs and the scattered settlements of Oakville and Rutherford reflect a period of established viticulture and trade long before the modern era of development.
