map_caption=The Brooks Range is a
mountain rangethat stretches from west to east across northern Alaskaand into Canada's Yukon Territory, a total distance of about 1100 km (700 mi). The mountains are not especially high, topping out at over 2,700 m (9,000 ft). This mountain range forms the northern-most drainage divide in North America, separating streams flowing into the Arctic Ocean and the North Pacific. The range roughly delineates the summer position of the Arctic front. It represents the northern extent of tree line, with no trees (apart from some isolated Balsam poplarstands) occurring north of the continental drainage divide. Mount Chamberlin, 9020 ft (2,749 m), is the highest peak in the range. Other notable peaks include Mount Isto, 8,975 ft (2,736 m) and Mount Michelson, 8,855 ft (2,699 m).Some sources (including the USGS1:250,000 scale map) quote Mount Isto's height as 9,050 ft, which would make it the highest point in the range. Also, some sources quote Mount Michelson's height as 9,239 ft, which would make it the highest point; however this is far above the 8,855 foot figure given on both USGStopographic maps, so it is unlikely to be correct.]
The range is mostly uninhabited, but the
Dalton Highwayand the Trans-Alaska Pipeline Systemrun through the Atigun Pass(1,415 m, 4,643 ft) on their way to the North Slope and the oil fields at Prudhoe Bay. The Alaska Nativevillages of Anaktuvuk and Arctic Village, as well as the very small communities of Coldfoot, Wiseman, Bettles, and Chandalar Lake are the only settlements in the 700-mile Brooks Range. In the far west, near the Wulik River in the De Long Mountains is the Red Dog Mine, Alaska, largest zinc mine in the world.
As one of the most remote and least-disturbed wildernesses of North America, the mountains are teeming with wildlife, including
Dall sheep, grizzly bears, and caribou.
The range was named by the USGS in 1925 after
Alfred Hulse Brooks, who was the chief USGS geologist for Alaska from 1903 to 1924.
Various historical records also referred to the range as the Arctic Mountains, Hooper Mountains, Meade Mountains and Meade River Mountains; the Canadian portion is still often referred to as the British Mountains. The British Mountains are part of
Ivvavik National Park.
