2023 Map of Onaqui Mountains South

About this map

The Onaqui Mountains form the backbone of this Tooele County survey, where the high ridges of Hellhole Canyon and Burnt Canyon descend toward the floor of Rush Valley. This arid landscape is defined by its water management and historical transit routes, most notably the Pony Express Rd skirting the southern foothills of Little Mtn. The map documents a sophisticated network of desert infrastructure, including the Aqueduct Rd, Pipeline Rd, and Waterline Rd, which reflect the logistical challenges of supporting life and industry in the basin. Occasional water sources like Hellhole Spring and Rock Canyon Spring provide rare points of relief in a terrain otherwise characterized by steep drainages like Skull Faust Canyon and East Faust Creek.
