Kachemak Bay State Wilderness Park is the state's only legislatively designated wilderness park.

Wildlife within the park includes marine mammals such as sea otters, sea lions, and whales, large land mammals such as moose and black bears, and numerous sea and land birds.  Terrain consists of both rocky and sandy beaches, dense mountain forests, and higher up, glaciers, and icefields. Because of the rugged conditions and unpredictable coastal weather, visitors are advised to be prepared for sudden wind, rain, or snowstorms at any time of year, especially at higher elevations, and to file a travel plan with rangers.  The park is mostly wild land, although there are a few cabins and semi-developed campgrounds.  The park ranger station is located in Halibut Cove Lagoon.

These are the first five tribes that Anglo-European settlers generally considered to be "civilized" according to their own worldview, because these five tribes adopted attributes of the colonists' culture, for example, Christianity, centralized governments, literacy, market participation, written constitutions, intermarriage with white Americans, and plantation slavery practices.  The Five Civilized Tribes tended to maintain stable political relations with the Europeans.
