About this map

Mare Island Navy Yard and the U.S. Arsenal dominate the southern maritime landscape of this turn-of-the-century survey, anchoring the industrial and military activity where the Napa River meets the Carquinez Strait. The map reveals a region defined by early viticulture and institutional development, with Napa Soda Springs and the Veterans Home established in the foothills. The complex network of the Southern Pacific and the Calistoga Branch railroads underscores the importance of freight and passenger transit between the valley and the bay.

Old land grants like Huichica and Caymus still influence the parceling of the terrain, while the extensive sloughs of the San Pablo Bay shoreline, including Napa Slough and Joice Island Creek, remain largely untamed. From the growing center of Napa to the coastal facilities at South Vallejo, the map documents a vital period of Northern California's transition into a modern agricultural and industrial hub.
