Organ Pipe Cactus National Monument dominates this desert landscape, where the United States Mexico border defines the southern limit of Pima County. The map captures a transition point between the La Abra Plain and the Puerto Blanco Mts, revealing an economy built on both border commerce and hard-rock mining. At the international line, Lukeville stands adjacent to the U S Customs and Immigration Reserve, while a series of remote mining operations like the Victoria Mine and Baker Mine dot the mountain slopes. Evidence of ranching and early desert survival is found at Dowling Ranch and scattered watering points such as Red Tanks Well and Pozo Salado Well. The rugged infrastructure of the mid-century monument is also visible, including the Puerto Blanco Drive and Monument Headquarters.
