Katmai National Park & Preserve

History of Katmai

A Volcanic Legacy, A Modern Priority

Katmai National Park and Preserve was created to conserve the famed Valley of Ten Thousand Smokes, a spectacular 40-square-mile, 100- to 700-foot-deep, pyroclastic ash flow deposited by Novarupta Volcano. Initially declared a national monument in 1918, Katmai preserved a living laboratory of its cataclysmic volcanic eruption six years earlier. Intervening years have seen most of the surface geothermal features cool. Even today, there are at least 14 volcanoes in Katmai considered "active" though none of these is currently erupting.
