1965 Map of Bannock Pass

About this map

Bannock Pass sits at the high-altitude junction of the Continental Divide and the state line between Montana and Idaho. This mid-1960s survey captures a landscape defined by its rugged topography and the remnants of industrial passage. The prominent Old RR Grade winds through the eastern portion of the map, illustrating the historical transportation corridor that once linked these mountain territories. Resource extraction is evident through features such as the Digmore Mine and various prospects scattered across Grizzly Hill and the surrounding slopes.
