Middle Fork Salmon River carves through the southern section of this map, marking a deep canyon system where Valley County and Custer County meet. This 2017 edition documents a landscape defined by the overlapping boundaries of the Boise National Forest and Challis National Forest. High points like Pungo Mtn and Grays Peak rise above a dense network of drainages including Middle Fork Indian Cr and Pungo Cr. A rare point of modern access and infrastructure is found at the Indian Creek USFS Airport, situated on a flat above the Indian Creek confluence. The map illustrates the complex topography of central Idaho, from the high alpine ridges to the river-level benches of Aquinaldo Flat, providing a detailed record of the wilderness trails and waterways that have remained largely unchanged for generations.
