1992 Map of Sun Valley

About this map

Sun Valley and Ketchum anchor the central valley of this 1990s-era topographic survey, which highlights the intersection of Idaho's resort developments and its industrial history. The Big Wood River provides the primary drainage through the Wood River Valley, where the mountain-bound settlements of Hailey and Triumph are situated. High-elevation peaks, including Hyndman Peak and Castle Peak, define the skyline across the Sawtooth Mountains, Boulder Mountains, and Pioneer Mountains. This map captures the region's complexity, showing the Sawtooth National Recreation Area alongside significant mineral extraction sites like the Triumph Mine and Phi Kappa Mine. Large alpine water bodies, such as Redfish Lake, Alturas Lake, and Pettit Lake, mark the northern reaches of the quadrangle, serving as focal points for the extensive protected lands of the Challis National Forest and Sawtooth National Forest.
