1910 Map of Bouldin

About this map

The intricate Delta landscape of the early 20th century is defined by a labyrinth of waterways surrounding massive islands and tracts. The San Joaquin River and Mokelumne River dominate the northern portion of the sheet, providing the primary arteries for commerce before the era of modern bridges and highways. Small riverside settlements and industrial outposts like Central Landing and the Old Cannery on Staten Island highlight the agricultural and canning economy that once thrived in these peat-rich lowlands. The complex network of sloughs, including Potato Slough and Criminal Slough, illustrates a time when the region relied heavily on water-based transport. Points of interest for researchers include family-named landmarks such as Hardscratch Pt and isolated water bodies like Turner Lake and Nibs Lake, which reflect the localized geography of the Mandeville Island and Venice Island areas before significant reclamation and modern alterations changed the face of the San Joaquin Delta.
