About this map

Mining operations and historical remnants dominate the high country along the Idaho-Utah border in this late 1950s survey. The northeast portion of the map reveals a concentrated cluster of industrial activity including the Vipont Mine, Skoro Mine, and several specialized features like the Phelan Tunnel and Harrison Tunnel. These workings are situated near Middle Mtn and Granite Pass, indicating a period of significant geological exploration in the region.

Further south, the landscape transitions into the drainage basins of Goose Creek and Basin Creek. Evidence of earlier settlement is found at Holt Basin (Ruins) and other scattered Ruins, while more modern infrastructure is represented by the Radio Relay Sta near Poison Cr. The terrain is marked by prominent peaks such as Twin Peaks and Beatty Mtn, with numerous Jeep Trails and trails providing the only access through the Grouse Creek Mountains.
