1925 Map of San Marcos 4-a

About this map

The San Marcos River corridor and its drainage network define this 1925 landscape as the region transitioned into early 20th-century agriculture and rail commerce. The Southern Pacific and San Antonio and Aransas Pass railroads intersect the terrain, providing essential transport for rural communities like Harwood and McNeil. The concentration of community structures, including Eba School and the Soda Springs Church, suggests a period of active rural settlement before the centralization of public services. Grounded in a 1925 survey by the State of Texas Board of Water Engineers, the map meticulously charts the winding courses of Plum Creek and West Fork Plum Creek as they move toward the larger river basin. This sheet is particularly valuable for tracing early school districts and church locations, such as Union Center School and Mt Zion Church, which served as the social anchors for this Texas landscape.
