2015 Map of Thayer Junction

About this map

Thayer Junction and Salt Wells sit within the high desert landscape of Sweetwater County, where the infrastructure of modern transit meets the faint tracks of the westward migration. The map documents a critical corridor where the historic Overland Trl route parallels the modern Interstate and rail lines, following the natural passage provided by Bitter Cr. This convergence of transportation eras highlights the enduring importance of this rugged path through the Great Divide Basin. To the south, Black Butte Cr and Salt Wells Cr drain through the arid terrain, while local routes like Salt Wells Ranch Rd and Salt Wells Rd provide access to the expansive rangelands. The topographical relief is most pronounced at Horsethief Canyon, a geographic landmark just south of the junction that further emphasizes the corridor's physical constraints.
