About this map

Benicia and the U.S. Arsenal anchor the southern shore of the Carquinez Strait in this early century study of the San Pablo and Suisun Bay connection. The landscape is defined by the complex aquatic network of the Suisun Marsh, where Suisun Slough and Montezuma Slough wind around Grizzly Island and Joice Island. On the opposite shore, the industrial and transit hubs of Martinez, Port Costa, and Crockett line the waterfront, serving as critical junctions for the Southern Pacific railroad and maritime traffic.

Upland from the marshes, the terrain rises into the Sulphur Springs Mt. and the ridge lines of Canada del Hambre. Maritime history is evident in named points and moorings like Rush Landing and Seal Bluff Landing, which reflect a period when small landings were vital for moving agricultural goods from the interior valleys to the bay. The map also captures the early footprints of settlements such as Fairfield and Cordelia before the extensive modern development of the North Bay corridor.
