President Donald Trump announced the name of Alaska’s highest peak — and North America’s tallest at over 20,000 feet — Denali, would be changed back to Mount McKinley. Trump was sworn in as the 47th president on Monday,

The president wants to honor a predecessor, William McKinley, by returning his name to North America’s highest peak. The state’s senators prefer the Native name.

In 2015, the name of the peak was changed during the Obama administration to reflect the traditions of Alaska Natives and preference of many Alaskans.
