2022 Map of Stillwell Crossing OE S

About this map

Big Bend National Park defines the northwestern corner of this study, where the arid landscape transitions into the protected canyonlands of the Chihuahuan Desert. The International Boundary with Mexico follows the path of the Rio Grande, specifically the segment designated as the Rio Grande Wild and Scenic River. This portion of the border is characterized by a network of seasonal drainages, such as Heath Cr, which feed toward the river through deeply etched arroyos. The map captures the isolation of this borderland region, documenting the protected wilderness and the natural course of the river before it continues its southeastward journey. It provides a technical record of the landforms and federal boundaries that shape the Big Bend frontier.
