Definition of katmai national park and preserve in English English dictionary
National park, southwestern Alaska, U.S., at the head of the Alaska Peninsula. Occupying an area of 4,090,000 acres (1,655,000 hectares), it was proclaimed a national monument in 1918 after the eruption of Novarupta in 1912. The eruption converted the valley into a wasteland known as the Valley of Ten Thousand Smokes, and the volcanic crater later became a lake. The park abounds in wildlife, including large numbers of brown and grizzly bears
