About this map

Rio Grande waters define the international boundary within Big Bend National Park, carving through the dramatic landscape of Boquillas Canyon. This 1971 survey captures the infrastructure of the border and park during a period of transition, following the Boundary Treaty of 1970. The settlement of Boquillas (Rio Grande Village) serves as a primary hub, supported by a Ranger Sta, US Customs, and a Research Sta.

Evidence of the region's rugged transport and industrial history remains visible through the Old Ore Road and the ruins of an Aerial Tramway (Terminal) near the river. Interior access is dictated by a network of primitive routes like the Strawhouse (Pack) Trail and Pack Trail that traverse the Sierra Del Caballo Muerto and Ernst Basin. Notable landmarks such as Hot Springs and the Boquillas Crossing (Ford) highlight the long-standing human connection to the river's edge.
