Challis National Forest dominates this high-altitude landscape in Custer County, defined by a dense network of mountain drainages and seasonal roads. The terrain is structured by the deep carving of Morgan Creek and its many tributaries, including West Fork Morgan Creek and Little West Fork Morgan Creek. Notable topographic landmarks include the prominent Red Butte in the south and the jagged Rye Grass Pinnacle to the east. The map captures the specialized infrastructure of this remote area, marking several routes as seasonal including the Morgan Creek Road and West Fork Morgan Creek Road, which provide access to high-basin features like Eddy Basin. From Millick Gulch to the headwaters of Blowfly Creek, the survey illustrates the complex hydrology of the Salmon River mountains before modern development.
