Wrangell–St. Elias National Park and Preserve
Mount St. Elias is the second highest mountain in both Canada and the United States. In total nine of the 16 highest peaks on U.S. soil are located in the park, along with North America's largest subpolar icefield, glaciers, rivers, an active volcano, and the historic Kennecott copper mines. Both the St. Elias and Wrangell ranges have seen volcanic activity. The St. Elias volcanoes are considered extinct, but some of the volcanoes of the Wrangell Range have been active in Holocene time. Ten separate volcanoes have been documented in the western Wrangell Range, of which Mount Blackburn is the highest and Mount Wrangell is the most recently active. Mount St. Elias is situated on the border of Wrangell–St. Elias National Park and Kluane National Park and Reserve. At ,
