1951 Map of Upper Valley

USGS Topo · Published 1951

About this map

Stocking Ranch and the Trail Guard Sta serve as the primary human markers in this high-elevation landscape of the Caribou National Forest. The geography is defined by parallel northwest-trending ridges including Rasmussen Ridge, the Webster Range, and the Wooley Range, which dictate the drainage patterns of the Blackfoot River and Lanes Creek. Several unnamed prospects suggest early mineral exploration across Rasmussen Valley and Dry Valley. The river carves through a tight topographic constriction known as The Narrows, while more remote stretches of the Upper Valley are fed by numerous small tributaries like Angus Creek and Diamond Creek. This 1949 survey provides a precise view of the region's topography before more modern developments, preserving the locations of cattle-range improvements and early forest service infrastructure.
