Dike Mountain is a 6,650-foot (2,027 m) glaciated summit located in the Boundary Ranges of the Coast Mountains, in the U.S. state of Alaska.[1] It is situated 26 miles (42 km) north-northwest of Juneau along the western side of the Juneau Icefield, on land managed by Tongass National Forest. Topographic relief is significant as the summit rises 1,150 feet (350 m) above the Eagle Glacier in 0.4 mi (0.64 km). Neighbors include Mustang Peak 0.8 mi (1.3 km) to the south, and Snowpatch Crag is 3.7 miles (6.0 km) to the east. Dike Mountain was named by members of the Juneau Icefield Research Project in 1964, and the toponym was officially adopted in 1965 by the U.S. Board on Geographic Names.[2][3]
Climate
[edit]Based on the Köppen climate classification, Dike Mountain is located in a subpolar oceanic climate zone, with long, cold, wet winters, and cool summers.[4] Most weather fronts originate in the Pacific Ocean, and travel east toward the Coast Mountains where they are forced upward by the range (orographic lift), causing them to drop their moisture in the form of rain or snowfall. As a result, the Coast Mountains experience high precipitation, especially during the winter months in the form of snowfall. Winter temperatures can drop below 0 °F with wind chill factors below −10 °F. This climate supports the West Branch Taku Glacier and Eagle Glacier surrounding the peak. The months May and June offer the most favorable weather for viewing this peak.
