2013 Map of Dorsey Butte

About this map

Dorsey Butte stands as a prominent landmark in this desert landscape where the borders of Ada, Elmore, and Owyhee counties meet. The southern portion of the map is defined by the sweeping curve of the Snake River, a vital water source that supports the agricultural activity visible on Chattin Flat. This 2013 survey illustrates the complex irrigation network essential to the region, featuring the Middle Line Canal and Low Line Canal which navigate the contours of the terrain below Chattin Hill. The area is interlaced with a grid of rural roads named for local families and early settlers, including Collett Rd, Shaw Rd, and Elmer Rd. The contrast between the natural drainages like Corder Cr and the engineered canal systems highlights the long-standing efforts to reclaim and farm this part of the Snake River Plain.
