1956 Map of Morrison Lake

About this map

Idaho-Montana borderlands are defined here by the high ridgelines of the Continental Divide Trail, where the Salmon National Forest meets the Beaverhead National Forest. This mid-century survey captures the remote character of the Lemhi Valley and the surrounding peaks, including Baldy Mtn and Tepee Mtn. Evidence of early resource extraction and high-altitude navigation is visible through the notation of a Shaft near Medicine Lodge Creek and several Prospect sites scattered through the canyons. The presence of a Landing Strip near Morrison Creek and various Jeep Trails underscores the reliance on specialized transport in this steep terrain. Water management is sparse but critical, evidenced by the Morrison Lake and a Reservoir tucked into the high drainages near Erickson Creek.
