Encyclopedia
The Talkeetna Mountains (Dghelaay tahwt’aene in Ahtna
) (62°2′N 147°54′W) are a mountain range in Alaska
. The Matanuska and Susitna River valleys, with towns such as Trapper Creek, Talkeetna, Wasilla, Palmer
, Sutton, and Chickaloon, roughly bound the Talkeetnas in the westerly parts of the range. Sovereign Mountain rises to 8849 feet in the remote and heavily glaciated central part of the range. The east side of the range fronts a broad, about 100-miles wide, lake-studded lowland of forests and swamps, across which rises the gigantic Mount Wrangell
(13,804 ft) volcanic edifice. Alaska Highway 4
runs northward through this lowland. Hundreds of miles to the west Alaska Highway 3 runs along the western side of the Talkeetna range, with the Alaska Range directly west. Alaska Highway 1
, running along the southern front of the Talkeetna Mountains, lies mainly in a valley marking a tectonic divide between the Jurassic
and Cretaceous
rocks of the accretionary wedge
, island-arc, and basement rocks in the Peninsular terrane (and other terranes forming the Talkeetna Mountains), and the Chugach Mountains
in the Chugach terrane to the south. The range stretches as much as a hundred miles north to south. Alaska Highway 8, seasonal and unpaved, passes over highlands rising to above 4000 feet, north of the Talkeetnas.
Hatcher Pass
, a seasonal highway pass across the southwestern corner of the range, provides views into the glaciated
interior of the range, and is the location of Independence Mine State Historical Park.
The majority of the land is state-owned, and it is home to many large mammal including grizzly/brown bear, black bear, moose, caribou, wolves, wolverine, and Dall sheep.
