2017 Map of Tuanna Butte

About this map

Bruneau Desert terrain dominates the landscape in this region of Twin Falls County, where the deep incisions of Salmon Falls Cr and Devil Cr cut through the high plains. The topography is defined by prominent volcanic features like Tuanna Butte and Devil Creek Butte, which serve as significant landmarks above the surrounding flats. The human imprint on the land is marked by a rigid grid of rural roads and the vital presence of the High Line Canal, illustrating the managed water systems necessary for activity in this arid environment. Significant elevation changes are visible at Blue Gulch and along the winding Lily Grade Rd, where the road descends toward the canyon floor, providing a detailed look at the interface between the desert floor and the drainage networks of the Snake River Plain.
