Caribou National Forest dominates this section of the Portneuf Range, where the high-altitude topography of the Idaho backcountry is defined by a dense network of canyons and gulches. The drainage patterns are intricate, with Pebble Creek and the Portneuf River drawing from numerous springs and forks like Big Spring and South Fork Toponce Creek. A robust system of historic trails and forest roads, including the Robbers Roost Trl and Hornet Canyon Trl, provides access to remote landmarks such as Horse Lakes. The map highlights the boundary between Bannock Co and Caribou Co, illustrating how the land was organized into townships and ranges within the national forest system, preserving a landscape that remains primarily defined by its natural water sources like King Creek Spring and Cold Spring.
