Denali National Park and Preserve is an American national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompass 6,045,153 acres (9,446 sq mi; 24,464 km2) which is larger than the state of New Hampshire. On December 2, 1980, 2,146,580-acre (3,354 sq mi; 8,687 km2) Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga, with tundra at middle elevations, and glaciers, snow, and bare rock at the highest elevations. The longest glacier is the Kahiltna Glacier. Wintertime activities include dog sledding, cross-country skiing, and snowmobiling. Denali is home to a variety of North American birds and mammals, including an estimated 300-350 grizzly bears on the north side of the Alaska Range (70 bears per 1000 square miles) and an estimated 2,700 black bears (334 per 1,000 square miles). As of 2014, park biologists were monitoring about 51 wolves in 13 packs (7.4 wolves per 1,000 square miles), while surveys estimated 2,230 caribou in 2013, and 1,477 moose in 2011. Dall sheep are often seen on mountainsides. Smaller animals such as coyotes, hoary marmots, shrews, Arctic ground squirrels, beavers, pikas, and snowshoe hares are seen in abundance. Red foxes, martens, lynxes, wolverines also inhabit the park, but are more rarely seen due to their elusive natures.
Many migratory bird species reside in the park during late spring and summer. There are waxwings, Arctic warblers, pine grosbeaks, and wheatears, as well as ptarmigan and the majestic tundra swan. Raptors include a variety of hawks, a variety of owls, and gyrfalcons, as well as the abundant but striking golden eagles.
