2020 Map of Dorsey Butte

About this map

Dorsey Butte and the surrounding high desert terrain define this landscape at the intersection of Ada, Elmore, and Owyhee counties. The southern portion of the quadrangle is shaped by the presence of the Snake River, where the elevation drops significantly from the open plateaus. Human engineering is evident in the network of irrigation systems, such as the Middle Line Canal and Low Line Canal, which divert water to support agriculture in the area of Chattin Flat. These canals represent the critical infrastructure necessary for settlement in this arid environment, contrasting with natural drainages like Corder Cr and Jack Cr. The map details a grid of rural roads, including Grandview Rd and River Rd, which provide access to the remote ranches and land parcels near Chattin Hill.
