Learn about the fascinating geologic landscape of City of Rocks National Reserve in southern Idaho with geology professor Shawn Willsey. Here he explains how the scenic fins, spires, and other bizarre rock shapes were formed from the 28-million-year-old granite that underlies much of the area.
You can learn more about southern Idaho geology by purchasing Geology Underfoot in Southern Idaho and Roadside Geology of Idaho. Both available locally or on Amazon.
