Fireweed Mountain is a prominent 6,956-foot (2,120 meter) mountain summit located in the Wrangell Mountains, in the U.S. state of Alaska. The peak is situated in Wrangell-St. Elias National Park and Preserve, immediately west of the terminus of the Kennicott Glacier, and west-northwest of McCarthy. Precipitation runoff from the eight-mile-long by five-mile-wide mountain drains into tributaries of the Chitina River, which in turn is part of the Copper River drainage basin. The mountain's name was given in the 1920s by Molly Gilmore, a lifelong resident of the McCarthy area, who at age 17, named the mountain for the abundance of fireweed which grew on the mountain following forest fires. Although fireweed is the most common and well-known flower in Alaska, it is not commemorated on any other Alaskan mountain. The mountain's name was officially adopted in 1966 by the U.S. Board on Geographic Names. On a clear day the summit of Fireweed Mountain offers views of Mount Blackburn to the northwest, and Regal Mountain to the northeast.
