Rio Grande waters define the western edge of this remote borderland quadrangle along the international boundary between Texas and Mexico. Located within Brewster Co, the map focuses on the protected wilderness of Big Bend National Park, specifically where the desert terrain meets the corridor of the Rio Grande Wild and Scenic River. The topography is dominated by the intricate drainage systems and arroyos that feed into the river basin, illustrating the stark natural landscape of the Trans-Pecos region. As a 2016 survey, it documents the preservation of this desert environment and the specific course of the river at a time of continued ecological focus in the American Southwest.
