Middle Fork Salmon River and Loon Creek dominate this 1962 landscape, where three National Forests—Salmon, Boise, and Challis—converge at the borders of Valley, Lemhi, and Custer Counties. The terrain is marked by remote outposts such as Tappen Ranch and essential backcountry infrastructure including the Simplot Airstrip and the Loon Creek Lookout at the southern edge. The river corridor provides a focal point for early recreation and accessibility, indicated by sites like Hospital Hot Spring, Hospital Bar Campground, and several river crossings including the Lower Loon Creek Bridge and White Creek Bridge. The map records small but significant human marks in the wilderness, such as a lone Grave near a Campground along the Middle Fork, reflecting the isolated nature of the Idaho interior during the mid-twentieth century.
