1996 Map of South of Bailey Peak

About this map

Tohono O'odham Indian Reservation lands meet the international boundary in this detailed survey of the borderlands south of the Lukeville area. The landscape transitions from the peaks of Sierra El Conejo and Sierra La Nariz into the expansive desert floor of The Great Plain. This map documents a cross-border environment where the ephemeral waters of the Sonoita river cross into Mexico, surrounded by ranching outposts and small settlements including Cuauhtémoc, El Conejo, and La Nariz. To the south, the map details several Mexican locales such as Rancho Lilón, División del Norte, and Veintiuno de Marzo (Fracción Uno). The presence of a remote Landing Strip near the northern mountains and the crossing of the Burro Pardo wash underscore the logistical and geographical character of this arid frontier region during the late twentieth century.
