1985 Map of Poison Canyon

About this map

Manti-La Sal National Forest dominates this mid-1980s provisional study, revealing a complex network of deep drainage systems and high plateaus. The topography is defined by the sharp descent from Elk Ridge into the Dark Canyon Wilderness, where Dark Canyon and its many tributaries, including Peavine Canyon and Horse Pasture Canyon, carve through the landscape. This map documents the area during a period of transition in land management, showing the Wilderness Boundary (Indefinite) established to protect these remote features.
