Ketchum Reservoir sits at the heart of this high-elevation landscape, where the rugged terrain of the Mount Hood National Forest meets the ridges of Wasco and Hood River counties. The area is defined by a series of high flats and prairies, such as Willow Flat, Round Prairie, and Pine Flat, which suggest a history of seasonal grazing or early upland settlement. Drainage systems like Mosier Creek and the North Fork Mill Creek carve through the prominent elevations of Sheldon Ridge and Mill Creek Ridge. Local landmarks like Old Schoolhouse Spring and the Sky Ranch Reservoir Number Three provide specific points of interest for those tracing the development of water resources and rural infrastructure in this part of Oregon. The map illustrates a complex network of forest roads, including Ketchum Rd and Fir Mountain Rd, navigating the steep transitions between canyons and peaks.
