2020 Map of Wild Horse Butte

About this map

Snake River canyon walls and high plateau desert dominate this modern topographical record of the Idaho borderlands. The river carves a deep path through the landscape, separating Thomas Flats on the northern bank from the prominent volcanic rise of Wild Horse Butte to the south. This rugged stretch of the canyon serves as the boundary between Ada Co and Owyhee Co, highlighting a region where terrain dictates political divisions. The presence of the Emigrant Trl tracing the southern benches above the river provides a tangible link to the historic overland migrations that once passed through this high desert. This 2020 edition documents the enduring physical landmarks of the Snake River Plain, where modern ranching infrastructure like Moore Rd meets the ancient topography of the western interior.
