2013 Map of Tuanna Butte

About this map

Tuanna Crossing sits at the heart of this high desert landscape, marking a historical point of passage in an area defined by dramatic geological transitions. The terrain shifts from the open expanse of the Bruneau Desert in the west to the deeply incised canyon of Salmon Falls Cr in the northeast. This 2013 survey illustrates the critical role of water management in the arid West, showing the High Line Canal skirting the canyon rim to provide irrigation. Local landmarks like Tuanna Butte and Devil Creek Butte rise above the surrounding plateaus, while drainage systems such as Devil Cr and Blue Gulch reveal the natural erosion patterns of the volcanic soil. The map also traces the modern road network, including Lily Grade Rd and House Creek Rd, which provide access to these remote Idaho rangelands.
