2023 Map of Tuanna Butte

About this map

Tuanna Butte and Devil Creek Butte rise as prominent geological landmarks above a landscape defined by deep canyon incisions and arid plateaus. The Salmon Falls Creek winds through the eastern portion of the quadrangle, joined by the deeply etched drainage of Devil Creek which cuts through the volcanic geology of the region. This 2023 survey illustrates the sparse, high-desert infrastructure of western Twin Falls County, where the rugged Bruneau Desert meets early agricultural irrigation systems like the High Line Canal. The map reveals a network of remote access routes including Lily Grade Rd and Big Bend Rd, reflecting the long-standing use of this terrain for ranching and resource management. The interplay between the natural watercourses and the gridded road system provides a clear view of the area’s modern-day land use patterns.
