Here's the history behind the name:
The peak was named Mount McKinley in 1896 after a gold prospector exploring the region heard that Ohioan William McKinley, a champion of the gold standard, had won the Republican nomination for president.
But Alaska natives had long before called the mountain Denali, meaning "the High One." In 1975, the state of Alaska officially designated the mountain as Denali, and has since been pressing the federal government to do the same.
Alaskans had been blocked in Congress by Ohio politicians, who wanted to stick with McKinley as a lasting tribute to the 25th U.S. president, who served from 1897 until his assassination in 1901.
Under Obama's action, Interior Secretary Sally Jewell will use her legal authority to end the long debate and rename the mountain.
The move elicited praise from Alaska Governor Bill Walker, a Republican turned independent, and Republican elected officials, who more typically are critical of an administration they see as hostile to the oil and gas interests of their state.
"I'd like to thank the president for working with us to achieve this significant change to show honor, respect, and gratitude to the Athabascan people of Alaska," said Republican Senator Lisa Murkowski, who led the fight for the Denali name in Congress.
I have a feeling Ataturk would find some way to criticize Obama if he cured cancer.
