Admiralty Island is an island in the Alexander Archipelago in Southeast Alaska, at . It is 145 km (90 mi) long and 56 km (35 mi) wide with an area of 4,264.1 km2 (1,646.4 sq mi), making it the seventh-largest island in the United States and the 132nd largest island in the world. It is one of the ABC islands in Alaska. The island is nearly cut in two by the Seymour Canal; to its east is the long, narrow Glass Peninsula. Most of Admiralty Island—955,747 acres (3,868 km2) —is protected as the Admiralty Island National Monument administered by the Tongass National Forest. The Kootznoowoo Wilderness encompasses vast stands of old-growth temperate rainforest. These forests provide some of the best habitat available to species such as brown bears, bald eagles, and Sitka black-tailed deer.
Angoon, a traditional Tlingit community home to 572 people, is the only settlement on the island, although an unpopulated section of the city of Juneau comprises 264.68 km2 (102.19 sq mi) (6.2 percent) of the island's land area near its northern end. The island's total population at the 2000 census was 650.
The national monument is considered sacred space to the Angoon Tribe of Tlingit people, who live on tribal land in the community of Angoon on the western coast of the island. The Tlingits fought to make protection for the island a part of ANILCA legislation, and continue to engage in stewardship of the island's natural resources. Most of Angoon's residents make daily subsistence use of the national monument.
The island was named by George Vancouver in honor of his Royal Navy employers, the Admiralty. Joseph Whidbey, master of the Discovery during Vancouver's 1791–95 expedition, explored it in July–August 1794, in the process circumnavigating it.
It was created December 1, 1978, by President Jimmy Carter. In the Alaska National Interest Lands Conservation Act Congress designated all but 18,351 acres (74 km2) of the monument as the Kootznoowoo Wilderness, ensuring that the vast bulk of this monument is permanently protected from development. The monument is administered by the U.S. Forest Service from offices in Juneau.
Western hemlock, Sitka spruce and western redcedar dominate the prolific rainforest vegetation; wildlife in abundance includes brown bear, bald eagles, many species of salmon, whales, and deer. Admiralty Island is home to the highest density of brown bears in North America. An estimated 1,600 brown bears inhabit the island, outnumbering Admiralty's human residents nearly three to one. It has more brown bears than the entire lower 48 states, and one of the highest densities of bald eagles in the world.
Murder Cove is located at the southernmost portion of the island and was home to the Tyee Company whaling station.
The Greens Creek mine is an underground silver, gold, zinc and lead mine located on the northwest end of the island, within the national monument. It began operations in 1989.
Admiralty Island offers opportunities for outdoor recreation. The 32-mile Cross Admiralty Canoe Route is a popular destination for backcountry canoeing and kayaking, traversing the breadth of the island through a series of lakes, streams and trail portages, with several cabins and shelters along the way. While the modern route was laid out and constructed by the Civilian Conservation Corps in the 1930s, it follows traces long used by the island's native inhabitants for hunting, fishing and trading.
The Pack Creek Brown Bear Viewing Area offers visitors the opportunity to observe brown bears in their natural habitat as they fish for salmon and interact with one another during the summer months. Permits are required for all visitors to Pack Creek; they can be obtained through the Forest Service.
The Point Retreat Light is located on the northern tip of Admiralty and was an important aid-to-navigation.
