1980 Map of Leadore

About this map

The high valleys of the Lemhi Range and Beaverhead Mountains define this 1980 survey, illustrating the rugged landscape along the Continental Divide. The settlement of Leadore serves as a central hub in the Lemhi Valley, flanked by the remains of the Old Railroad Grade and an Old Indian Reservation Boundary that speaks to the region's complex administrative history. The map captures a transitional moment for the local economy, documenting mining operations like the Copper Queen Mine, Irma Mine, and Digmore Mine alongside vast stretches of the Salmon National Forest and Beaverhead National Forest. To the west, the Pahsimeroi Valley and the community of Patterson are set against peaks such as Yellow Peak and Sheephorn Peak, while unique place names like Chinatown and Leadville offer clues to early mountain settlements and prospecting camps.
