By establishing Gates of the Arctic National Park & Preserve (GAAR) in Alaska’s Brooks Range, Congress has reserved a vast and essentially untouched area of superlative natural beauty and exceptional scientific value – a maze of glaciated valleys and gaunt, rugged mountains covered with boreal forest and arctic tundra vegetation, cut by wild rivers, and inhabited by far-ranging populations of caribou, Dall sheep, wolves, and bears (barren-ground grizzlies and black bears). Congress recognized that a special value of the Park and Preserve is its wild and undeveloped character, and the opportunities it affords for solitude, wilderness travel, and adventure. Gates of the Arctic encompasses several congressionally recognized elements, including the national park, national preserve, wilderness, six Wild Rivers and two National Natural Landmarks. The National Park Service is entrusted to manage this area to protect its physical resources and to maintain the intangible qualities of the wilderness and the opportunity it provides for people to learn and renew its values.
