Tour of Park Geology - Volcano Parks

Volcanic processes are constantly changing the Earth. Eruptions can create new islands, build and destroy mountains, and alter landscapes. Active, dormant, and ancient remnants of eruptions are all contained within our National Parks. Many features we see when visiting the National Parks are created by volcanic processes such as geysers, ash flows, and hot springs. Visit the links on this page to learn more about the different types of volcanoes, the rocks created from eruptions, and the landforms that exist because of volcanic processes in the National Parks.
