There is no federal law naming "Mt McKinley"

Here is the text of the Mt McKinley act of 1917.    It names a park.  Not a Mountain.

Here is a description of the federal act that among other things changed the name to Denali National Park.

The Dept of the Interior is charged with naming federal lands and they answer to the president.

Once again, Wingnuts, you are wrong, obtuse, and willfully ignorant.   Spare me your fake outrage and--as always--go fuck yourselves.
