2011 Map of Upper Valley

About this map

Stocking Ranch and the Maybey Canyon Phosphate Mining Area highlight the dual nature of land use in this part of Caribou County during the early 21st century. The landscape is defined by the Blackfoot River as it winds through Rasmussen Valley, squeezed by the prominent Rasmussen Ridge. Further south, the river passes through a restrictive canyon known as The Narrows. Industrial activity is concentrated at the southern edge of the map, where the large-scale phosphate mining operations of Mabey Creek and Dry Valley dominate the terrain. A network of forest and county roads, including Diamond Creek Rd and Lanes Creek Rd, provide access to the remote creeks and drainages like Timothy Creek and Bacon Creek that feed into the larger river systems.
