2013 Map of Wild Horse Butte

About this map

Snake River canyons cut a dramatic path through the volcanic plateau of southern Idaho, marking the boundary between Ada and Owyhee counties. This 2013 topographic study documents the arid landscape surrounding Wild Horse Butte and Thomas Flats, where the river's descent is utilized at Swan Falls. The mapping reflects a region defined by its historic transit corridors and modern water management. Most notably, the path of the Emigrant Trl is preserved across the southern sections of the map, tracing the ancestral route of pioneers through this desert terrain. The local infrastructure is a network of utilitarian roads such as S Swan Falls Rd and Abendroth Rd, which provide access to the river valley and the high desert flats above the rimrock.
