The Federal Aviation Administration issued a charting notice Monday detailing the changes of "Gulf of Mexico" to "Gulf of America" and the Alaskan peak "Denali" to "Mount McKinley."
The notice said that changes "will be targeted for the next publication cycle."
"This Charting Notice implements President [Donald] Trump's direction in Executive Order 14172, 'Restoring Names That Honor American Greatness,' that the names be changed," according to the guidance.
Trump by proclamation recognized Sunday "as the first ever Gulf of America Day."
"Today, I am making my first visit to the Gulf of America since its renaming. As my Administration restores American pride in the history of American greatness, it is fitting and appropriate for our great Nation to come together and commemorate this momentous occasion and the renaming of the Gulf of America," he wrote.
