1985 Map of Poison Canyon

USGS Topo · Published 1985

About this map

Manti-La Sal National Forest dominates this mid-1980s landscape, where a complex network of canyons and high plateaus defines the terrain of San Juan County. The drainage patterns are intricate, with Poison Canyon and Deadman Canyon cutting deep into the mesas, eventually feeding into the Dark Canyon system. Higher elevations are marked by North Elk Ridge and Horse Mtn, offering a view of the topographic isolation of the Colorado Plateau.
