About this map

Rasmussen Valley and the surrounding high-elevation terrain of Caribou National Forest define this landscape within the northern Rocky Mountains. The Blackfoot River flows through the central corridor, joined by tributaries like Lanes Creek and Diamond Creek. The topography is marked by significant north-south trending formations, including the Webster Range to the east and Rasmussen Ridge to the west.

Evidence of human presence is concentrated around water sources and recreational infrastructure, such as the Mill Canyon Campground. The transition from the Lower Valley to Dry Valley is carved by Dry Valley Creek, while narrow passages like The Narrows highlight the constraints of the local hydrology. This 2020 record details a complex network of forest access routes, including Blackfoot River Rd and the Old Road 1257, supporting both resource management and outdoor activity in the high country.
