2010 Map of Seminole Canyon

About this map

The Rio Grande forms the international boundary between the United States and Mexico in this arid borderland survey. This map illustrates the convergence of major waterways within the Amistad Reservoir, where the Pecos River joins the primary river channel. The landscape is defined by deep incisions like Seminole Canyon, which carves through the limestone terrain toward the reservoir's edge. Human presence in this frontier region is largely confined to infrastructure and ranching access, evidenced by the transit of Zubenbueler Ranch Rd. The survey provides a clear view of the water levels and shoreline configuration of the reservoir as it appeared in the early 21st century, illustrating how the dammed waters have transformed the original canyons and river bends of the border.
