There’s something unique about each part of Idaho, including its local geology. The museum has an extensive collection of rocks, minerals, and gems from each region—from the mining districts of northern Idaho, the rocky batholith of Idaho’s central mountains, and the volcanically active Snake River plain.
These study guides (requires Adobe Reader) highlight each of Idaho’s mining districts, whose minerals are on display at the museum: Northern Idaho, East Central Idaho, West Central Idaho, South Central Idaho, Southwest Central Idaho, Southeastern Idaho, Southwestern Idaho, Far Western Idaho.
