The confluence of the Gunnison River and the Colorado River anchors this detailed study of the Grand Valley, where the high desert meets an intricate network of early twentieth-century irrigation engineering. The landscape is defined by extensive water management systems, including the Government Highline Canal, Main Line Grand Valley Canal, and Orchard Mesa Canal Number 1, which transformed this arid region into a productive agricultural and residential hub.
