About this map

Rio Grande meanders along the international boundary in this remote southern Texas survey, where the river serves as the definitive border between the United States of America and Estados Unidos Mexicanos. The landscape is defined by the stark isolation of the Big Bend region, featuring only sparse human imprints like the small settlements of Pantera and Talley. These locales sit near the river’s edge, reflecting a historical reliance on the watercourse for survival in a desert environment. The sparse labeling underscores the wilderness character of the area, providing a precise record of these isolated frontier outposts and their proximity to the shifting channels of the border river.
