1972 Map of Rough Canyon

About this map

Amistad Reservoir dominates this landscape in the early 1970s, where the rising waters of the Rio Grande basin have transformed the arid canyons of Val Verde County. The map documents the development of the National Recreation Area, showing how the impoundment reached into the steep-walled Rough Canyon and the winding course of the Devils River. Human activity at this time is centered on recreation and burgeoning lakeside settlements, as seen at Devils Shores and the infrastructure around the Rough Canyon Marina. High-water marks like Elevation 1114 and Elevation 1117 indicate the shifting shoreline and submerged terrain. Away from the water, Recreational Road No 2 provides access through the high limestone plateaus, connecting the shoreline to the interior of the Texas borderlands.
