2010 Map of Bourland Canyon

About this map

Rio Grande waters define the international boundary between the United States of America and Mexico in this arid borderland survey. The landscape is dominated by a complex network of dry washes and deep incisions, most notably the winding path of Maravillas Canyon and its tributary, Maravillas Creek. These drainage systems converge at the Mouth of the Maravillas, a critical geographic junction near the historical Maravillas Crossing. Human presence is sparse, centered primarily on the isolated Pettit Ranch, which sits amidst a series of named topographic features including Dog Canyon and Bourland Canyon. The map reveals the stark intersection of natural geology and political borders, where the rugged terrain of Horse Canyon and Driftwood Canyon spills toward the river's edge.
