1989 Map of Borah Peak
USGS Topo · Published 1989About this map
Borah Peak and the high summits of the Lost River Range dominate this 1980s landscape, where deep glacial valleys separate massive mountain blocks. The map reveals a high-altitude ranching and mining environment characterized by broad alluvial fans like Barton Flats and Sunny Bar. Small, isolated settlements such as Gilmore and Nicholia anchor the edges of the Birch Creek Valley, while the Wilbert Mine and Sentinel Mine suggest the region's enduring connection to mineral extraction.
