The Geology of Idaho is complex, with outcroppings of differing ages of volcanics, undifferentiated metamorphics and sedimentary structures.

Since 1919, the Bureau of Mines and Geology of Idaho has studied and reported on the general and environmental geology of the state.The Bureau was renamed the Idaho Geologic Survey in 1984. The organization also studies and reports on the water (both surface and ground), mineral data, and energy assets of the state. [1]
Geologists and hydrologists on staff at the agency research, make reports based on their research, and produce maps for the state. The University of Idaho administers the program in Moscow and in Boise (Boise State University) and Pocatello (Idaho State University.)
The region of the Idaho Panhandle reaches from the Canadian border south to Interstate Highway 90. The area consists generally of Precambrian sedimentary formations, some of which have metamorphosed into slates. The area includes the Selkirk Mountains, the Purcell trench and the Cabinet Mountains. Lead, silver and other ores are mined in the Coeur d’Alene Mining District.[2]
