2013 Map of Jackass Butte

About this map

The Snake River carves a deep path through this corner of the Idaho desert, defining the boundaries between Ada, Elmore, and Owyhee Counties. The landscape is dominated by stark basalt features and wide alluvial benches, most notably Jackass Butte and Black Butte, which rise above the river's winding course. Evidence of historic overland travel and modern agricultural efforts are visible side-by-side, with the historic Emigrant Trl cutting across the northwestern terrain while the Grand View Irrigation District Canal and Middle Line Canal bring water to the arid flats. Remote outposts like Bonus Cove Ranch and named landmarks such as Big Foot Bar and Chattin Flat provide specific points of reference for local historians and geographers. The map also detail numerous seasonal drainages, including Cloudburst Wash and McKeeth Wash, which illustrate the region's flash-flood hydrology.
