About this map

Big Bend National Park dominates the northwest corner of this remote borderland survey, where the international boundary between the United States and Mexico follows the winding course of the river. The deep incision of Mariscal Canyon marks a dramatic geological transition as the Rio Grande cuts through the desert floor. This area is further protected as the Rio Grande Wild and Scenic River, a designation that reflects the preserved state of the waterway and its surrounding environment. The terrain is characterized by a dense network of intermittent drainage channels that feed into the river from the high desert of Brewster County and Coahuila. This survey captures a landscape defined almost entirely by its natural hydrology and international borders, with no roads or settlements visible in the immediate vicinity.
