About this map

The Blackfoot River carves through the heart of this Caribou County landscape, winding through Upper Valley where it is joined by Lanes Creek and Diamond Creek. This 1949 survey period captures the area's transition from open range to managed forest within the Caribou National Forest, punctuated by isolated outposts like the Stoeking Ranch and the Trail Guard Sta. The terrain is dominated by prominent north-south elevations including Rasmussen Ridge and the Webster Range, which frame the agricultural and grazing lands below.

Evidence of early exploration and mineral interest is scattered across the ridges, with various Prospect and Prospects sites noted near the Wooley Range. The hydrological network is remarkably dense, featuring named points such as Campbell Spring and Chicken Spring Creek. Notable geological features like The Narrows and Diamond Canyon illustrate the complex drainage patterns that defined local travel and land use during the mid-century.
