The high-altitude drainage systems of Routt National Forest characterize this mid-century survey of the North Park region. The landscape is defined by its complex irrigation infrastructure, including the Oldenburg Ditch, Garland Ditch, and Flying Dutchman Ditch, which redirect water across the valleys for ranching operations. Significant cattle and agricultural centers like the Jack Creek Ranch and Roslyn Ranch are established near the confluence of the Illinois River and Jack Creek.
