2017 Map of Jackass Butte

About this map

Jackass Butte and Black Butte dominate the high ground above the winding Snake River in this arid landscape where the borders of Ada, Elmore, and Owyhee counties converge. This 2017 study illustrates the modern geography of the Snake River valley, showing the persistent influence of water and transport on the local terrain. Long-established routes like the Emigrant Trl and Big Foot Bar Rd track the river's edge, connecting points like Big Foot Bar and Chattin Flat. The development of agriculture and infrastructure is evidenced by the Grand View Irrigation District Canal and more modern additions like Missile Base Rd. Numerous washes and gulches, including Cloudburst Wash and Vinson Wash, score the landscape, while Rabbit Springs provides a rare point of named hydrology away from the main river corridor.
