Was Denali the highest mountain in the US used to be named?

Denali, the highest mountain in the United States, was formerly known as Mount McKinley. The name was officially changed back to Denali in 2015, reflecting its original Alaskan Native name, which means "the high one." The name Mount McKinley was given in honor of President William McKinley, but it was largely used by those outside of Alaska. The reversion to Denali acknowledges the mountain's cultural and historical significance to the Indigenous people of the region.
