Saint Elias Mountains
The Saint Elias Mountains are a subgroup of the Pacific Coast Ranges, located in southeastern Alaska in the United States, southwestern Yukon and the very far northwestern part of British Columbia in Canada. The range spans Wrangell-St. Elias National Park and Preserve in the USA and Kluane National Park and Reserve in Canada and includes all of Glacier Bay National Park in Alaska. In Alaska, the range includes parts of the city/borough of Yakutat and the Hoonah-Angoon and Valdez-Cordova census areas.
This mountain range was named after Mount Saint Elias which had been named in 1741 by the Danish explorer Vitus Bering.〔

== Geology ==
Although most of the range is non-volcanic, portions at the western end near the Wrangell Mountains are volcanic. This region includes two major stratovolcanoes, Mount Churchill and Mount Bona, the latter being the highest volcano in the United States. West of the Saint Elias Mountains is the still-active Fairweather Fault, which is the northward extension of the Queen Charlotte Fault. The St. Elias range is a result of 10 million years of the North American tectonic plate pushing material up as it overrides the Pacific plate, then the material being worn down by glaciers.
