1979 Map of Rilda Canyon

About this map

Manti-La Sal National Forest dominates this section of the Wasatch Plateau, where the boundary between Sanpete and Emery counties follows high ridges like Bald Ridge. The landscape is defined by a series of deep canyons and seasonal drainages, including Rilda Canyon, Crandall Canyon, and Horse Canyon, which carve through the high elevations. While much of the area remained protected forest land in the late 1970s, evidence of resource extraction and survey work appears in the form of multiple Drill Holes and scattered Mines along the canyon walls.
