1979 Map of Rilda Canyon

About this map

The high plateau country of the Manti-La Sal National Forest is defined by deep incisions and resource extraction in the late 1970s. The landscape is dominated by a series of parallel drainages, most notably Rilda Canyon and Mill Fork, where several Mines are noted along the steep canyon walls. This survey captures a moment when the canyon floors served as primary arteries for energy production and cattle management, evidenced by the network of jeep trails and numerous marked drill holes scattered across the uplands.
