1901 Map of Carquinez

About this map

Benicia and the U.S. Arsenal anchor this late-nineteenth-century survey of the critical waterways connecting the California coast to the interior. The landscape is defined by the complex hydrology of Suisun Bay and the Carquinez Strait, where a dense network of tidal channels like Peytonia Slough and Montezuma Slough weave around Grizzly Island. The map captures the industrial and maritime character of the region before mid-century development, showing the established waterfronts of Vallejo and South Vallejo alongside growing rail-dependent towns.
