About this map

Caribou National Forest dominates this section of the Idaho backcountry, where the high-altitude terrain of the Fall Creek Basin meets the county line. The landscape is defined by an intricate network of drainage systems, including Peterson Creek, Beaver Creek, and Monument Creek, many of which originate from numerous unnamed and named Springs like Willow Springs. These water sources were vital for the seasonal livestock operations indicated by the Fall Creek Cow Camp in the northeastern corner. Transportation through this complex topography was limited to primitive routes like the Skyline Road and the Boundary Trail, which trace the ridges and divides. The prominent landmark of Castle Rock stands near the boundary between Bonneville and Bingham counties, serving as a natural navigational beacon for those traversing the high country.
