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.
Regal Mountain
Regal Mountain is an eroded stratovolcano or shield volcano in the Wrangell Mountains of eastern Alaska. It is located in Wrangell-Saint Elias National Park about east of Mount Blackburn, the second highest volcano in the United States, and southeast of the massive Nabesna Glacier. Regal Mountain is the third highest thirteener (a peak between 13,000 and 13,999 feet in elevation) in Alaska, ranking just behind its neighbor, Atna Peaks. Because the mountain is almost entirely covered in glaciers, no geological studies have been done, but published references state and the geological map shows that the mountain is an old eroded volcanic edifice.
