1968 Map of Pinnacle Canyon

About this map

Bad Land Cliffs dominate the northern landscape of this 1968 field-checked survey, marking a stark geographic boundary between high plateaus and the deep drainages below. The winding course of Nine Mile Creek cuts through the center of the sheet, carving a significant valley that serves as a primary corridor through this complex terrain. To the south, the broad expanse of Horse Bench provides a rare area of level ground above the branching systems of Rock House Canyon and Pinnacle Canyon. The map records the intersection of Duchesne and Carbon counties amidst a network of canyons including North Franks, South Franks, and Desbrough Canyon. Evidence of mid-century exploration is noted by a Drill Hole near the southern edge of the survey, while a single Trail and various fence lines suggest the limited human activity and livestock management in this rugged section of the Utah wilderness.
