1968 Map of Porcupine Ridge

USGS Topo · Published 1970

About this map

Porcupine Ridge dominates the western landscape of this high-altitude border region where the state lines of Utah and Wyoming meet. Surveyed in the late 1960s, the terrain is defined by a series of high-desert drainages and seasonal watercourses, including Howard Creek, Thief Creek, and Chicken Creek. To the northeast, Barker Reservoir and Sage Creek suggest the vital role of water management in this arid environment. The map details a network of primitive transportation and infrastructure, showing several Jeep Trails that navigate the slopes near Porcupine Mtn and a prominent Pipeline cutting through the southern half of the quadrangle. The eastern portion transitions into the Chalk Creek Basin, a significant topographic depression where Chalk Creek flows toward the county line between Summit and Uinta counties.
