2013 Map of Norton Ridge

About this map

Norton Ridge dominates the skyline of this central Idaho landscape, where the high-altitude divide separates the drainages of the Boise National Forest and Challis National Forest. The map reflects a remote wilderness character defined by its dramatic elevation changes, punctuated by tactical vantage points like the Norton Ridge Lookout and Mahoney Creek Lookout. Human activity is sparse and concentrated near water sources, evidenced by the Marble Creek Ranch and Cameron Ranch along the southern reaches of the quadrangle. The intricate drainage network of Mahoney Cr and Marble Cr feeds eventually toward the Middle Fork Salmon River, which cuts through the southeastern corner. This survey documents the intersection of Valley and Custer counties during the early 21st century, providing a clear record of forest service land management and natural topography.
