The Rio Grande valley southeast of El Paso serves as the agricultural and transportation heart of this 1939 survey. The intricate network of irrigation, including the Franklin Canal, San Elizario Main Canal, and Mesa Drain, illustrates the transformation of the desert floor into productive land around Clint and Fabens. Parallel tracks of the Southern Pacific and Texas and Pacific railroads dominate the corridor, highlighting the importance of rail transit to the regional economy. Beyond the valley, the landscape shifts abruptly to the arid Mesa and the striking Rimrock formation. To the northeast, the terrain is marked by isolated outposts like Roberts Ranch and Riddleman Well (Abandoned), alongside geological curiosities such as Moving Dunes. This map documents a period when rural ranching and intensive river-valley farming existed side-by-side on the San Elizario Island.
