The United States of America Estados Unidos Mexicanos international boundary winds along the path of the Rio Grande in this survey of the South Texas brushland northwest of the urban center. This landscape is defined by the sharp contrast between the arid, dissected uplands and the river corridor that separates Texas from Mexico. Development is concentrated along the northeastern edge of the sheet, where the outskirts of Laredo meet the industrial and transport corridor of Mines Rd. The interior of the map reveals a complex network of ephemeral drainages and ranch tracks typical of the borderlands, offering a detailed view of the terrain before it meets the river's edge. This recent topographic record captures the topographical relief and modern infrastructure of a region critical to trade and international geography.
