1967 Map of Phi Kappa Mtn

About this map

Phi Kappa Mines and several smaller Mines and Prospects dot the high elevations of the Pioneer Mountains on the boundary of Custer and Blaine Counties. This high-altitude landscape is defined by its drainage systems and glacial features, where Big Fall Creek, Summit Creek, and Phi Kappa Creek carve through the deep valleys of the Challis National Forest. The map documents a primitive transportation network consisting of a Jeep Trail following the creek beds and numerous Pack Trails that provided access to remote peaks like Handwerk Peak and the distinctive formation known as The Devils Bedstead. High-mountain basins hold a series of alpine waters, including Washington Lake, Boulder Lake, and Kane Lake. The transition between the Challis and Sawtooth National Forest is clearly delineated across Duncan Ridge, reflecting the mid-century management of these public lands.
