About this map

Challis sits at the northwestern edge of this landscape, serving as a gateway to the complex drainage systems of the Salmon River. The river winds through the center of the map, fed by numerous tributaries including Hannah Slough and Birch Cr. The topography is defined by significant elevation changes between the lowlands of Round Valley and the high, open spaces of Bradbury Flat and Germer Park.

A network of named rural roads, such as Challis Hot Springs Rd and Bingville Rd, reveals the pattern of ranching and remote settlement in this part of Custer County. To the south, Germer Basin and Bishop Spring highlight the essential water sources in an otherwise arid environment. The map details a transition from the structured street grid of the town site to the expansive, gulch-cut terrain where Bradbury Gulch and Mud Spring Gulch descend toward the river valley.
