Katmai National Park contains more volcanoes than any other national park in the entire United States (13 volcanoes). This cluster of closely spaced active volcanoes includes two caldera which are each filled with a deep caldera lake. One of these complexes is known as Kaguyak, which produced a major explosive eruption 5800 years ago. Although it has not erupted for some time, carbon dioxide and other volcanic gasses regularly bubble up in its lake, indicating that an at depth magma chamber is still present. • If you would like to support this channel, consider becoming a patron at / geologyhub . • Another way to support this channel is to make an order via our gemstone and geology related etsy store at http://prospectingarizona.etsy.com. • This channel's merch store is also on etsy at http://geologyhub.etsy.com. • Graphics of eruption dates are courtesy of the Global Volcanism Program, Smithsonian Institute. https://volcano.si.edu/ • Google Earth imagery used in this video: ©Google Data Providers • Thumbnail Photo Credit: Nye, C.
