Copter Peak is a 4250feet mountain summit in Alaska, United States.
Copter Peak is part of the De Long Mountains which are a subrange of the Brooks Range.[1] It is set 115miles north of Kotzebue and 450miles northwest of Fairbanks in the Noatak National Preserve. Although remote, Copter Peak is a popular area to visit in Noatak National Preserve because of a nearby backcountry landing strip west of the peak.[5] The mountain provides habitat for Dall sheep and the Alaska marmot.[5] Precipitation runoff from the mountain drains into tributaries of the Kugururok River which in turn is a tributary of the Noatak River. Topographic relief is significant as the southeast slope rises approximately 2450abbr=offNaNabbr=off in 0.9miles. The mountain was so named by Donald J. Orth of the U.S. Geological Survey because of a difficult helicopter landing there in 1956.[4] [6] The mountain's toponym has been officially adopted by the United States Board on Geographic Names.[4]
According to the Köppen climate classification system, Copter Peak is located in a subarctic climate zone with cold, snowy winters, and cool summers.[7] Winter temperatures can drop below −20 °F with wind chill factors below −30 °F.
