All National Monuments Designated Under the Antiquities Act

Grand Staircase-Escalante

Bob Wick/BLM

The designation of a national monument is a recognition of the space’s contribution to America’s heritage, whether through its rich natural beauty or the role it’s played in our developing national story. Nearly every president since Theodore Roosevelt has made use of his Antiquities Act authority to create monuments. And together, they’ve woven a colorful fabric representing America. To remove any thread would be a travesty.
