1991 Map of Alta

USGS Topo · Published 1991

About this map

The West Fork Bitterroot River carves through the center of this terrain, anchoring a landscape shaped by mining activity and forestry at the Montana-Idaho border. The settlement of Alta serves as a focal point near the Alta Recreation Site, while smaller sites like Cooper Place suggest more isolated habitation. Mining history is evident through the presence of the Lucky Joe Mine and the Copper Queen Mine, alongside various unnamed shafts and adits that point to the region's extractive past. High points such as Thunder Mountain and Wilkerson Ridge define the verticality of the Bitterroot National Forest, where numerous drainages like Hughes Creek and Chicken Creek feed into the primary river system.
