2013 Map of Bourland Canyon

About this map

The Rio Grande snakes through a complex drainage network along the Texas-Mexico border, anchoring a landscape defined by deep canyons and isolated outposts. In the northern reaches, Dog Canyon and the seasonal Maravillas Cr dictate the topography, eventually leading south toward the Pettit Ranch. The convergence of these watercourses is marked by the Mouth of the Maravillas, a critical geographic junction near the historic Maravillas Crossing. To the south, the terrain becomes increasingly intricate as the river winds past Bourland Canyon and Driftwood Canyon, reflecting the traditional ranching and riverfront patterns of this remote borderland. The map documents the persistent connection between limited water sources and human habitation in this arid environment.
