1987 Map of Lowry

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.
