The Pioneer Mountains define the high country of this mid-century survey, where the rugged terrain of the Beaverhead National Forest is deeply scarred by a century of hard-rock mining. The southeastern corner of the map reveals a concentrated industrial landscape centered around Ermont Mill and several nearby extractions like the Ermont No 2 Mine and Badger Mine. These operations were served by the Ermont Road, which follows the natural corridor of Rattlesnake Creek as it winds toward the valley. Further north, the map documents a transition from mining to ranching, with the Pilon Ranch and Carroll Ranch occupying the lower slopes. A notable historical relic, the Coke Kiln near Little Bear Gulch, suggests the early presence of smelting operations used to process ores from the surrounding claims.
