2011 Map of South of Somerton

About this map

Border Rd cuts a sharp diagonal across this arid landscape south of Somerton, tracing the international boundary line in the early 21st century. The map reveals a transition from the structured agricultural grid of Yuma County to the open desert terrain. Key transit corridors like S Avenue B and Avenue F terminate at or near this demarcation, illustrating the rigid geometry of the borderlands. The network of rural roads, including Co 23rd St S and Co 24 St, provides a detailed look at the local infrastructure supporting the region's agricultural and security-focused landscape. This survey by the U.S. Geological Survey preserves the exact placement of these routes and the sparse layout of the terrain just before subsequent developments in border infrastructure.
