1951 Map of Dry Valley

USGS Topo · Published 1951

About this map

Caribou National Forest dominates this Idaho landscape, where a series of family ranches line the narrow valleys between high ridges. Based on aerial photography from 1947 and a 1949 field check, the survey reveals a remote high-altitude ranching economy centered around Schmid Ridge. The drainage of Slug Creek and Dry Valley Creek provides the primary geography for these scattered operations, including the Stewart Ranch, Young Ranch, and Petterson Ranch. The map also details early prospecting efforts through various prospect sites, particularly near the Dry Basin. Administrative presence is noted at the Dry Valley Guard Sta, while the rugged terrain is carved by named draws like Caldwell Canyon and Hornet Canyon. This documentation offers a precise record of the mid-century grazing and mineral exploration footprint in eastern Idaho.
