Kootznoowoo Wilderness

The indigenous people of southeast Alaska, the Tlingit, know Admiralty Island by the name Kootznoowoo, the "Bear Fort" or "Fortress of the Bears". The British named it Admiralty, but the Russians called it Ostrov Kutsnoi, "Fear Island", probably because Alaskan brown bears (grizzly) outnumber the human inhabitants. Protected as Admiralty Island National Monument in 1978, all but the northern end of the island was designated Wilderness in 1980. Coastal forests of massive Sitka spruce and western hemlock dominate this 100-mile-long island at the northern end of the fabled inside passage. The forest floor lays thickly covered with mosses and blueberry, while muskegs open the tall forest canopy to sedge and sphagnum bogs.
