About this map

The international border along the Rio Grande defines this 1970s survey of the river's Big Bend corridor. Within the protected boundaries of Big Bend National Park, the landscape is marked by the massive Sierra Del Caballo Muerto and the sharp relief of Boquillas Canyon. Cultural and administrative presence is concentrated at Boquillas (Rio Grande Village), where a Ranger Sta, US Customs, and a Boquillas Crossing (Ford) facilitated cross-border movement and park management.

Historically significant routes like the Old Ore Road and several pack trails, including the Strawhouse Trail and Marufa Vega Trail, provide evidence of earlier mining and ranching logistics. An Aerial Tramway Terminal on the slopes above Ernst Valley points to specialized industrial operations, likely related to the transport of minerals from the nearby mountain ranges to the river valley floor. The map also captures local landmarks such as Hot Springs and the Rio Grande Overlook, documenting the intersection of early tourism and rugged desert topography.
