2024 Map of Dorsey Butte

About this map

Dorsey Butte and Chattin Hill command the high ground of this high-desert landscape south of the Boise area, where the agricultural plains of Chattin Flat meet the military operations of the Orchard Combat Training Center. The region's economy is clearly defined by its water management, centered on the complex irrigation network of the Middle Line Canal and Low Line Canal which divert resources toward the fertile land above the Snake River. This 2024 survey documents the modern rural infrastructure of Elmore County, from family ranch access points like E Nicholson Ranch Rd to the seasonal drainage of Corder Creek and Jack Creek. The map provides a precise look at the township and range intersections where the borders of Ada, Owyhee, and Elmore counties converge near the river's path.
