1978 Map of Garns Mtn

About this map

The mining history of the Big Hole Mountains is recorded in detail on this 1978 sheet, where numerous shafts and prospects dot the high-elevation ridges of the Targhee National Forest. Clusters of activity center on Hillman Mine and Packsaddle Mine, while the Idaho Mine sits high on Idaho Ridge. These sites are linked by a complex network of pack trails and jeep trails that navigate the steep drainages of Packsaddle Creek and Hillman Creek. The landscape is dominated by notable summits like Garns Mtn and Ryan Peak, providing a clear look at the logistical challenges of extraction in the Teton Basin region. Remote landmarks such as Blacktail Pass and Government Trail Pass offer specific reference points for researchers tracing the old access routes into the Idaho mountains.
