1971 Map of Onaqui Mts South

USGS Topo · Published 1974

About this map

The Pony Express Road skirts the southern edge of the high country in this early 1970s survey, following a route historically vital to transcontinental communication. This landscape is defined by the sharp rise of the Onaqui Mountains, where steep drainages like Skull Faust Canyon, Hellhole Canyon, and Rock Canyon cut through the western slopes. Water sources are scarce but critical in this arid environment, marked by Hellhole Spring and Rock Canyon Spring. To the east, the terrain descends into the broad expanse of Rush Valley, where a modern Aqueduct parallels the mountain range. The map also records early industrial and resource extraction activity through scattered Quarries, a Prospect, and a Borrow Pit, while numerous Jeep Trails provide access through the rugged foothills of Davis Knolls and Post Hollow.
