Katmai Wilderness
The Katmai Wilderness, located within Katmai National Park and Preserve, is characterized by active volcanoes, pristine lakes and rivers, glaciated peaks, and rugged coastline. The area contains the famed Valley of Ten Thousand Smokes, a spectacular forty square mile, 100 to 700 foot deep ash flow deposited by Novarupta Volcano in June of 1912 during a major cataclysmic eruption. In addition to Novarupta, the Katmai Wilderness contains many other active volcanoes, including Katmai, Trident, Mageik, Martin, and Fourpeaked. The area is home to an abundance of wildlife. The most widely known is the brown bear, which resides throughout the coastal and lake regions of the Wilderness.
