Geology of Idaho

Idaho's geologic history dates back over 2.5 billion years, with the formation of its oldest rocks in the Precambrian era. The state's landscape was shaped by various geologic processes, including volcanism, tectonic forces, and erosion.

During the Paleozoic and Mesozoic eras, Idaho was mostly covered by shallow seas, which led to the deposition of sedimentary rocks and the formation of marine fossils. It was also during this time that the state experienced significant tectonic activity and mountain building events, such as the Antler and Sevier orogenies.

In the Cenozoic era, volcanic activity played a major role in shaping Idaho's landscape. The Columbia River Basalt Group, which covers a large portion of the state, formed from massive lava flows. The hotspot responsible for the Yellowstone supervolcano also passed through Idaho, leaving behind a trail of volcanic features, such as the Craters of the Moon National Monument and Preserve.

Idaho's rich mineral resources are a result of its varied geologic history. The state is known for its silver, lead, zinc, and copper deposits, as well as gemstones like opal, garnet, and jasper. This diverse geology has made Idaho an attractive destination for rockhounding enthusiasts and geology enthusiasts alike.
