William McKinley
In 1896, a gold prospector gave McKinley's name to Denali, the tallest mountain in North America at . The Alaska Board of Geographic Names changed the name of the mountain back to Denali in 1975, which is what it was called by locals. The Department of the Interior followed suit in August 2015 as a part of a visit to Alaska by President Barack Obama. Similarly, Denali National Park was known as Mount McKinley National Park until December 2, 1980, when it was changed by legislation signed by President Jimmy Carter.
Wrangell–St. Elias National Park and Preserve
Wrangell–St. Elias National Monument was designated on December 1, 1978, by President Jimmy Carter using the Antiquities Act, pending final legislation to resolve the allotment of public lands in Alaska. Establishment as a national park and preserve followed the passage of the Alaska National Interest Lands Conservation Act in 1980. The park has long, extremely cold winters and a short summer season. Plate tectonics are responsible for the uplift of the mountain ranges that cross the park. The park's extreme high point is Mount Saint Elias at , the second tallest mountain in both the United States and Canada. The park has been shaped by the competing forces of volcanism and glaciation. Mount Wrangell is an active volcano, one of several volcanoes in the western Wrangell Mountains. In the St. Elias Range, Mount Churchill has erupted explosively within the past 2,000 years. The park's glacial features include Malaspina Glacier, the largest piedmont glacier in North America, Hubbard Glacier, the longest tidewater glacier in Alaska, and Nabesna Glacier, the world's longest valley glacier. The Bagley Icefield covers much of the park's interior, which includes 60% of the permanently ice-covered terrain in Alaska. At the center of the park, the boomtown of Kennecott exploited one of the world's richest deposits of copper from 1903 to 1938, exposed by and in part incorporated into Kennicott Glacier. The abandoned mine buildings and mills comprise a National Historic Landmark district.
