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.
Black Tooth Mountain
Black Tooth Mountain () is located in the Bighorn Mountains in the U.S. state of Wyoming. The peak is the second highest in the range after Cloud Peak, which is only to the south, and the summit is located in the Cloud Peak Wilderness of Bighorn National Forest. The sharp dark profile of the mountain resembles a dark tooth or fang, hence the name. Because of the steep terrain, Black Tooth Mountain is one of the hardest mountains to climb in the Bighorns. Many of the trails up the mountain are unmarked which adds to the difficulty of reaching the summit. Mount Woolsey is an adjacent summit only to the southeast. Another high peak of the Bighorns known as Hallelujah Peak is situated along a knife-like ridge known as an arête to the northeast. Several tiny remnant glaciers can be found on the north slopes of Black Tooth Mountain.
