Stikine-LeConte Wilderness
Encyclopedia
The Stikine-LeConte Wilderness is on the mainland of southeast Alaska
, southeast of Petersburg
and north of Wrangell, Alaska
. The boundary extends from Frederick Sound
on the west to the Alaska-Canada
boundary on the east. The wilderness is 448841 acres (181,639.7 ha) in size. It is part of Tongass National Forest
, which is managed by the United States Forest Service

, which flows through the southern portion of the Stikine-LeConte Wilderness. The river valley is relatively narrow. The surrounding mountains are steep, rugged, and contain numerous glacier
s. Meltwater from these glaciers has a high silt
content, giving the Stikine River a milky appearance. The river delta
is highly braided with three main navigable channels. Two warm and one hot spring
s are found along the river. North of the Stikine River area is the LeConte Glacier
, which flows into LeConte Bay
. LeConte Glacier is the southernmost glacier in North America that flows directly into salt water. Mountains in the area of LeConte Bay are steep and most of the upper valleys are glacier-filled. Glaciers and ice fields cover most of the rugged, mountainous area in the eastern part of the Stikine-LeConte Wilderness.
Alpine vegetation, including moss
es, lichen
s, and other small plants, is found at the upper elevations. The lower mountain slopes near salt water support a dense spruce

rainforest
. Closer to the Canadian border, the rain decreases and the vegetation changes to stands of cottonwood. Cottonwood are also common on the many islands of the Stikine. The valley floor along the river is a combination of muskeg
s and dense alder
and willow
thickets. The Stikine River delta is approximately 17 miles (27.4 km) wide and consists of grass flats, tidal marsh
, and sand bars.
Much of the area, particularly the Stikine River drainage, is recognized as an important fish and wildlife area. Moose

s, brown bear
