2017 Map of Wild Horse Butte

About this map

Snake River canyon walls dominate this portion of the Idaho landscape where Ada and Owyhee counties meet. The high plateau above the river is marked by the distinctive Wild Horse Butte and the historic route of the Emigrant Trl, which winds through the southern terrain toward the river's edge. This 2017 survey by the U.S. Geological Survey illustrates a sparsely populated region defined by agricultural water access and topographic elevation changes, with Thomas Flats serving as a localized point of interest near the water. Modern infrastructure such as S Swan Falls Rd and Moore Rd provide access across the section lines of the Public Land Survey System, highlighting the ongoing human footprint on this high desert terrain.
