The mining history of the Missoula and Granite county line is clearly visible in this 1960s topographic record. The settlement of Coloma sits high on a ridge near the Coloma Cem, surrounded by a cluster of workings including the Clemantha Mine and Mammoth Mine. Further west, the rugged topography reveals the Copper Cliff Mine and Leonard Mine tucked into the headwaters of Union Creek.
