1910 Map of Castle

About this map

The Calaveras River and Bear Creek define the hydrologic character of this Central Valley landscape, which was surveyed at a pivotal moment for San Joaquin County agriculture. The terrain is notably influenced by the Woodbridge Irrigation Canal, illustrating the early 20th-century transition toward engineered water management for local farming. This 1907-1908 field survey captures the intersection of three major rail lines, including the Southern Pacific R. R. and the Western Pacific R. R., which facilitated the movement of goods between rural outposts.
