1963 Map of Potaman Peak

About this map

Challis National Forest dominates this mid-century topographic study, defined by the convergence of the Salmon River and the East Fork Salmon River. The high-elevation interior is marked by significant alpine features, including the prominent Potaman Peak and the high-altitude Railroad Ridge in the southwest corner. The drainage patterns are intricate, with Sullivan Creek feeding into the namesake Sullivan Lake, while other alpine basins hold Jimmy Smith Lake and Big Lake.
