1947 Map of Wild Horse Butte

About this map

Wild Horse Butte rises above the canyon floor in this post-war Idaho landscape, marking a prominent bend in the Snake River. The terrain is defined by the sharp contrast between the high desert plateaus and the deep river gorge, which serves as the border between Ada Co and Owyhee Co. Evidence of early river crossings and water access is scattered throughout the canyon, including a Ferry located near Swan Falls at the northern edge of the sheet. Along the riverbanks, distinct topographical benches like Thomas Flats and Big Foot Bar offer glimpses into the unique landforms of the Snake River Plain. Small water sources, including Fossil Cr and various Springs, are precious landmarks in this arid environment, showing the natural points of interest for early settlers and travelers through the region.
