Falconberry Peak and Grouse Creek Peak dominate this high-elevation landscape within the Challis National Forest. The map documents a complex drainage system defined by the prominent Loon Creek, which is fed by numerous tributaries including Yellow Cat Cr, Horse Cr, and Burn Cr. This survey illustrates the intricate topography of Custer and Lemhi counties, where the land is carved by the Castle Fork and Cliff Cr. Human passage through this steep terrain is limited to routes like the Grouse Creek Rd, which traces the lower elevations near Grouse Cr. The map provides a look at the wilderness character of the region, showing the convergence of various creek systems and the prominence of landmarks such as Loon Creek Point in a region largely defined by its natural watersheds.
