The tallest mountain in the United States has been officially reverted to Mount McKinley, the U.S. Department of the Interior announced in a press release Friday. The official action comes four days after President Donald Trump signed an executive order on his first day back in office that also changes the name of the Gulf of Mexico to the Gulf of America.

The president made the name change through one of dozens of executive orders he signed on Monday. Former President Barack Obama’s administration ordered that the mountain be renamed as Denali in 2015.

Renaming Denali back to Mount McKinley, along with renaming the Gulf of Mexico the Gulf of America, will be among the nearly 200 day-one executive orders Donald Trump is expected to sign after being sworn into office for his second term as president, according to published reports.
