1968 Map of Pinnacle Canyon

About this map

Bad Land Cliffs dominate the northern terrain of this 1968 survey, giving way to a deeply incised landscape where the Duchesne Co and Carbon Co line follows the winding course of Nine Mile Creek. This drainage serves as the primary geographic axis for a network of named tributary canyons including Desbrough Canyon, Devils Canyon, and Franks Canyon. The map documents a period of remote land use characterized by a solitary Jeep Trail and a scattered Drill Hole, signifying early mineral or geological exploration.
