About this map

Water management and agricultural infrastructure dominate the landscape of the Montana high plains in the late 1980s. The intricate network of irrigation systems, including the Greenfields Main Canal, Sun River Canal, and Spring Valley Canal, illustrates the intensive engineering required to sustain ranching and farming in this arid region. These man-made waterways cut across natural features like Big Coulee and Loomis Coulee, channeling water from the Teton River toward the dry flats.

Small-scale settlement is centered around the Hamilton Ranch and the small station at Lowry, located near the intersection of Teton, Lewis and Clark, and Cascade counties. The terrain is marked by significant landforms such as Moehler Hill and the School Section Coulee, while industrial activity is evidenced by several Gravel Pits and the Radio Facility Fairfield near the eastern boundary. This document provides a clear look at the intersection of natural drainage and modern hydraulic manipulation in Big Sky Country.
