Grand Mesa National Forest dominates the upper reaches of this mid-1960s survey, where the rugged terrain of Durkee Ridge and Hells Hole gives way to a complex network of high-altitude water management. The landscape is defined by its engineering, featuring the Overland Canal, Highline Canal, and numerous irrigation ditches such as Dever Ditch and Stingley Ditch that traverse the slopes of Redlands Mesa and Cedar Mesa.
