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.

Denali–Mount McKinley naming dispute
The name of the highest mountain in North America became a subject of dispute in 1975, when the Alaska Legislature asked the U.S. federal government to officially change its name from "Mount McKinley" to "Denali". The mountain had been unofficially named Mount McKinley in 1896 by a gold prospector, and officially by the Federal government of the United States in 1917 to commemorate William McKinley, who was President of the United States from 1897 until his assassination in 1901.
