2011 Map of Challis

About this map

Challis serves as the focal point of this Custer County landscape, situated at the junction of several vital waterways and canyons. The Salmon River flows prominently through the central valley, flanked by the braided channels of Hannah Slough and fed by Garden Creek and Challis Creek near the town center. To the north, the terrain transitions into a series of named gulches and high points, including McNabbs Point and Round Valley, illustrating the complex drainage patterns of the region. This 2011 survey documents the layout of local infrastructure such as the Challis Airport and the Penal Gulch Access Area, alongside rural routes like Darling Creek Rd that provide access to the surrounding heights. The map records a modern settlement pattern deeply influenced by the original water sources and natural corridors of the Idaho interior.
