History
The Antiquities Act authorized permits for legitimate
archaeological
Archaeology or archeology is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of Artifact (archaeology), artifacts, architecture, biofact (archaeology), biofacts or ecofacts, ...
investigations and penalties for taking or destroying antiquities without permission. Additionally, it authorized the president to proclaim "historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest" on federal lands as national monuments, "the limits of which in all cases shall be confined to the smallest area compatible with the proper care and management of the objects to be protected."
Presidents have used the Antiquities Act's proclamation authority not only to create new national monuments but to enlarge existing ones. For example, Franklin D. Roosevelt significantly enlarged
Dinosaur National Monument in 1938.
Lyndon B. Johnson added
Ellis Island to
Statue of Liberty National Monument in 1965, and Jimmy Carter made major additions to
Glacier Bay and Katmai National Monuments in 1978.
Early 20th century origin
The
Antiquities Act of 1906 resulted from concerns about protecting mostly prehistoric
Native American ruins and artifacts (collectively termed "antiquities") on federal lands in the American West.
The reference in the act to "objects of ... scientific interest" enabled President Theodore Roosevelt to make a natural

In response to Roosevelt's declaration of the Grand Canyon monument, a putative mining claimant sued in federal court, claiming that Roosevelt had overstepped the Antiquities Act authority by protecting an entire canyon. In 1920, the
United States Supreme Court

ruled unanimously that the Grand Canyon was indeed "an object of historic or scientific interest" and could be protected by proclamation, setting a precedent for the use of the Antiquities Act to preserve large areas.
Federal courts have since rejected every challenge to the president's use of Antiquities Act preservation authority, ruling that the law gives the president exclusive discretion over the determination of the size and nature of the objects protected.

. He did this to accept a donation of lands acquired by
John D. Rockefeller Jr., for addition to
Grand Teton National Park after Congress had declined to authorize this park expansion. Roosevelt's proclamation unleashed a storm of criticism about use of the Antiquities Act to circumvent Congress. A bill abolishing Jackson Hole National Monument passed Congress but was vetoed by Roosevelt, and Congressional and court challenges to the proclamation authority were mounted. In 1950, Congress finally incorporated most of the monument into Grand Teton National Park, but the act doing so barred further use of the proclamation authority in Wyoming except for areas of 5,000 acres or less.
Late 20th century and early 21st century
The most substantial use of the proclamation authority came in 1978, when President
Jimmy Carter
James Earl Carter Jr. (October 1, 1924December 29, 2024) was an American politician and humanitarian who served as the 39th president of the United States from 1977 to 1981. A member of the Democratic Party (United States), Democratic Party ...
proclaimed 17 new national monuments in Alaska after Congress had adjourned without passing a major Alaska lands bill. Congress passed
a revised version of the bill in 1980 incorporating most of these national monuments into national parks and
preserves, but the act also curtailed further use of the proclamation authority in Alaska.
Carter's 1978 proclamations included

Bureau of Land Management. This action was unpopular in Utah, and bills were introduced to further restrict the president's authority, none of which have been enacted.

National Landscape Conservation System.

In December 2017, President Donald Trump substantially reduced the sizes of
Bears Ears and
Grand Staircase–Escalante National Monuments, removing protections on about 2.8 million acres of land where mining could resume.
[Keith Schneider]
Trump dramatically shrinks two national monuments in Utah, assailing rule by 'distant bureaucrats'
''Los Angeles Times'' (December 4, 2017). Three lawsuits challenged the legality of this action in federal court, and in October 2021, President Joe Biden reversed the changes. The restoration of the monuments has been challenged in court in an attempt to attack the Antiquities Act.
President Biden's proclamations establishing and expanding monuments often incorporated consultation with Native American tribes for management and planning.
In 2025, Trump's interior secretary Doug Burgum ordered a review of all withdrawn public lands including national monuments for their exploitation for drilling and mining.
