1949 Map of Fivemile Pass

About this map

The boundary between Tooele Co and Utah Co cuts through this high desert terrain, where the northern end of Rush Valley meets the rising slopes of the Thorpe Hills. The landscape is defined by its strategic passages, notably Fivemile Pass, Sevenmile Pass, and Tenmile Pass, which have historically dictated transportation routes through this part of the Great Basin. Transportation history is particularly evident here; while the Union Pacific line remains active in the north, a (Dismantled Railroad) branches south toward the settlement of Topliff, hinting at the area's waning mining or industrial activity in the late 1940s. Beyond the rail lines, the presence of an Airway Beacon and Topliff Hill serve as essential navigational landmarks for both ground and air travel across this arid expanse.
