The Tusk (Alaska)

The Tusk is a 6650. ft mountain summit in Alaska, United States.

Description
The Tusk is located in the Boundary Ranges of the Coast Mountains and set on land managed by Tongass National Forest. The remote peak is 4 mi east of Horn Spire and 24 mi north of Juneau on the northwest margin of the Juneau Icefield. Precipitation runoff and glacial meltwater from the mountain drains west to Berners Bay and Lynn Canal via the Gilkey River. Topographic relief is significant as the summit rises 5,450 feet (1,660 m) above the Battle Glacier in 2 mi.

History
The mountain's descriptive name was applied by members of the Juneau Icefield Research Project in 1964 and the toponym was officially adopted in 1965 by the United States Board on Geographic Names. The first ascent of the summit was made on August 2, 1972, by Fred Beckey, John Rupley, Dave Beckstead, and Ray Ketcham via the upper Taku Glacier.

Climate
Based on the Köppen climate classification, The Tusk is located in a tundra climate zone with long, cold, snowy winters, and cool summers. Weather systems coming off the Gulf of Alaska are forced upwards by the Coast Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop to 0 °F with wind chill factors below −10 °F. This climate supports the Taku Glacier, Battle Glacier, Gilkey Glacier, and the Juneau Icefield surrounding the peak.
