Gates of the Arctic Wilderness is a wilderness area in the U.S. state of Alaska
. Located in the Gates Of The Arctic National Park
and Preserve, it is 7,245,600-acre (2,932,200 ha) in area, the third-largest designated wilderness area in the United States
(after the Wrangell
-Saint Elias Wilderness and the Mollie Beattie Wilderness, both also in Alaska).
When the wilderness activist, Bob Marshall
, for whom Bob Marshall Wilderness in Western Montana is named explored the region in the early 1930s he bestowed the name "The Gates of the Arctic" on a pair of mountains near the head of the North Fork of the Koyukuk River
(Boreal Mountain and Frigid Crags).
The wilderness is home to many animals, including grizzly bears, moose, wolves, Dall sheep, black bears, and many smaller mammals. Barren-ground caribou congregate in large herds. The rivers are home to many schools of fish, including the Grayling
, arctic char and chum salmon. Eagles and other birds of prey can seen soaring overhead waiting for unsuspecting prey.
