1957 Map of Edie Ranch

About this map

The Continental Divide serves as the primary geographic spine for this high-altitude borderland, separating the Beaverhead National Forest of Montana from the Targhee National Forest in Idaho. This 1957 field-checked survey highlights a remote ranching and grazing landscape where Edie Ranch sits along the upper reaches of Medicine Lodge Creek. The terrain is defined by significant summits like the Red Conglomerate Peaks and Heart Mtn, with drainage networks including Webber Creek and Crooked Creek cutting through the high country. Small-scale human activity is evidenced by an isolated Prospect and several noted springs, such as Big Spring and Warm Springs. The presence of Antelope Lakes and Hollow Lake provides water sources in an otherwise drainage-dominated landscape, which remains largely roadless except for light-duty routes like the one leading toward Bannack Pass.
