The Portneuf Range and its network of deeply etched canyons form the backbone of this high-elevation Idaho landscape within the Caribou National Forest. The map details a complex system of drainage and movement, where seasonal and perennial waters like S Fork Toponce Cr and N Fork Pebble Cr flow through named features such as Bear Camp Gulch and New Canyon. Evidence of land use is visible in the spidering forest roads and trails, including the Bear Camp Trail and the evocatively named Robbers Roost Boundary Trail. This 2020 record of the Bannock and Caribou county line shows a terrain defined by its water sources, from the isolated Big Spring to the high Trail Canyon Springs, highlighting the critical importance of these features in the arid high country.
