The Brooks Range (Athabaskan ''Gwazhał''〔(USGS )〕 is a mountain range in far northern North America stretching some 1100 km (700 mi) from west to east across northern Alaska into Canada's Yukon Territory. Reaching an elevation exceeding 2,700 m (9,000 ft), the range is believed to be approximately 126 million years old. In the United States, these mountains are considered an extension of the Rocky Mountains, whereas in Canada they are considered separate, the northern border of the Rocky Mountains regarded as the Liard River far to the south in the province of British Columbia.〔(The Encyclopedia Americana ), Volume 23, page 618 (Grolier 2000).〕〔Safire, William. (The New York Times guide to essential knowledge: a desk reference for the curious mind ), page 623 (Macmillan 2007 ).〕 While the range is mostly uninhabited, the Dalton Highway and Trans-Alaska Pipeline System run through the Atigun Pass (1,415 m, 4,643 ft) on their way to the oil fields at Prudhoe Bay on Alaska's North Slope. The Alaska Native villages of Anaktuvuk and Arctic Village, as well as the very small communities of Coldfoot, Wiseman, Bettles, and Chandalar Lake, are the range's only settlements. In the far west, near the Wulik River in the De Long Mountains is the Red Dog mine, largest zinc mine in the world. The range was named by the United States Board on Geographic Names in 1925 after Alfred Hulse Brooks, 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, a part of Ivvavik National Park. ==Peaks== * Mount Chamberlin at 9020 ft (2,749 m) : * Mount Isto at 8,975 ft (2,736 m) : * Mount Michelson at 8,855 ft (2,699 m) : * The Gates of Kiev at 7,775 ft (2,370 m), the highest point in the central part of the range, and : * Black Mountain at 5,020 ft (1,530 m), the highest point in the far western part of the range. : * Mount Doonerak : * Mount Igikpak : * Frigid Crags West Gate : * Boreal Mountain East Gate : * Limestack Mountain : * Cockedhat Mountain 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Brooks Range」の詳細全文を読む スポンサード リンク
