President Donald Trump says he’s changing the official name of Alaska’s — and North America’s — tallest peak from Denali back to Mount McKinley. It’s the latest chapter in a long struggle over what the mountain should be called.

The tallest peak in North America has been named Denali since 2015 when its name was officially changed under former President Barack Obama.

The move is likely to face some pushback in Alaska, where the Alaska Native name has long been favored for the continent’s tallest mountain.
