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.
Clifton Maloney
Maloney was an accomplished mountaineer who at the time of his death was believed to be the oldest American ever to summit an "Eight-thousander", one of the fourteen peaks in the world that are greater than 8,000 meters in altitude. He climbed five of the "Seven Summits", the tallest mountains on each of the seven continents, including Denali in Alaska, Mount Kilimanjaro in Africa, the Vinson Massif in Antarctica, Aconcagua in the Andes, and Mount Elbrus in the Caucasus. On September 24, 2009, at the age of 71, Maloney summited the nearly 27,000-foot peak of Cho Oyu, the world's sixth-highest mountain, in Tibet. He reached the summit of the "Turquoise Goddess", as the mountain is known, with the help of a sherpa and a guide, Marty Schmidt. He then descended to Camp 2 at 23,000 feet. On the morning of September 25, 2009 he woke up and told a companion, ""I'm the happiest man in the world -- I have just climbed a beautiful mountain."" These were apparently his last words as he went back to sleep and never woke up.
