What is a national monument?
National monuments are designated to afford protection, conservation, and restoration to landscapes of tremendous beauty, diversity, and historic or scientific interest.

Why do national monuments exist?
The Antiquities Act of 1906 granted the President authority to designate national monuments in order to protect “objects of historic or scientific interest.” While most national monuments are established by the President, Congress has also occasionally established national monuments to protect natural or historic features. Since 1906, the President and Congress have created more than 100 national monuments. National monuments are currently managed by agencies including the BLM, National Park Service, Forest Service, and Fish and Wildlife Service.
