Stikine Icecap
Encyclopedia
The Stikine Icecap is a large icefield straddled on the Alaska
–British Columbia
boundary in the Alaska Panhandle
region. It lies in the Boundary Ranges
of the Coast Mountains
. Within the United States, most of it is under the administration of the Tongass National Forest
and is part of the Stikine-LeConte Wilderness
within the national forest.
An extremely large icefield, the icecap is a primary source for both the Taku River
, which forms its northern boundary, and the Taku's southern tributaries, and also the Stikine River
and its lower western tributaries, notably the Chutine
, which form its southern and southwestern boundary, respectively. The Stikine Icecap is the parent icefield of the LeConte
and Sawyer Glaciers on its US side, and the Great Glacier
on its Canadian side. Also on the Canadian side and entering the lower Stikine, like the Great Glacier, are the Mud and Flood Glaciers, which form the boundaries of the small Boundary Range
, which is an eastern abutment of the range comprising the Stikine Icecap and marks the approximate boundary claimed by the United States prior to the Alaska Boundary Settlement
of 1903.
The Stikine Icecap area is also renowned for its technically demanding and dangerous peaks and spires of granite that have garnered comparisons as North America's version of Patagonia
. Peaks of particular renown include Devils Thumb
, Witches Tits, Cat's Ears, and the Burkett Needle.
Most expeditions into the region usually depart from Petersburg, Alaska
