Mining camps and isolated ranches define this high-elevation landscape along the international boundary in the late 1950s. The dense concentration of silver, lead, and copper claims in the Patagonia Mountains is evident through sites like Harshaw, Washington Camp, and Duquesne. Numerous smaller operations such as the Mowry Mine and Endless Chain Mine dot the slopes of American Peak and Mt Washington, showing the intensity of 19th and early 20th-century extraction. To the east, the terrain opens into the San Rafael Valley, where the headwaters of the Santa Cruz River flow through a broad cattle-grazing territory marked by family holdings like the Heady-Ashburn Ranch and Greene Ranch. At the southern edge, the border settlement of Lochiel sits directly on the United States Mexico line, featuring the US Customhouse and the Fray Marcos de Niza Historic Monument, which commemorates early Spanish exploration through this pass into the interior.
