In 1912, the Novarupta Volcano erupted, filling the valley with a 100- to 700-foot-deep ash flow.
While Katmai was originally created to preserve this "Valley of 10,000 Smokes," today’s park protects deep valleys, glacial moraines and lakes along a line of active volcanoes and the waters of the Cook Inlet.
One of the primary purposes of Katmai National Park is to protect the habitats of brown bears, spawning salmon,
and the other species that have brought life to the volcanic landscape. In addition to wildlife, over 700 species of plants are found in the park.
What is the role of the Endangered Species Act?
National parks would not be complete without the animals and plants that call them home. The Endangered Species Act is the most important tool to make sure species vital to the parks are protected for the long term.
