Owl Mountain dominates the northern reaches of this mid-century survey, its slopes marked by a high Lookout Tower and the headwaters of numerous creeks within the Routt National Forest. The landscape is a complex network of high-altitude water management, where the Illinois River and Michigan River systems are interconnected by an extensive series of man-made channels, including the Oldenburg Ditch, Garland Ditch, and Parkview Ditch.
