The Mule Mountains dominate the northern landscape of this borderlands survey, where the rugged southern Arizona terrain meets the international boundary between the United States and Mexico. This era of mineral extraction is well-documented through a network of active and former workings, including the Glance Mine, Marquette Mine, and the Crook Tunnel. The industrial footprint extends to the transportation infrastructure, featuring the active Southern Pacific line alongside an Old Grade Railroad, tracing the evolution of ore transport toward the Sulphur Springs Valley. While much of the land remains undeveloped mining territory, the presence of the Christiansen Ranch and several scattered water reservoirs highlights the localized ranching and water management essential for survival in the high desert of Cochise County.
