In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the President of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance.
The 129 national monuments are managed by several federal agencies: the National Park Service, United States Forest Service, United States Fish and Wildlife Service, the Bureau of Land Management, and the National Oceanic and Atmospheric Administration (in the case of marine national monuments). Historically, some national monuments were managed by the War Department.
The Antiquities Act of 1906 gives presidents the power to proclaim national monuments by executive action. President Theodore Roosevelt used the act to declare Devils Tower in Wyoming as the first U.S. national monument.
The Antiquities Act authorized permits for legitimate archaeological 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.
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 geological feature, Devils Tower in Wyoming, the first national monument three months later. 800,000 acres (3,200 km2) of the Grand Canyon as a national monument.Among the next three monuments he proclaimed in 1906 was Petrified Forest in Arizona, another natural feature. In 1908, Roosevelt used the act to proclaim more than
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.
In 1918, President Woodrow Wilson proclaimed Katmai National Monument in Alaska, comprising more than 1,000,000 acres (4,000 km2). Katmai was later enlarged to nearly 2,800,000 acres (11,000 km2) by subsequent Antiquities Act proclamations and for many years was the largest national park system unit.
Petrified Forest, Grand Canyon, and Great Sand Dunes, among several other national parks, were also originally proclaimed as national monuments and later designated national parks by Congress.
Substantial opposition did not materialize until 1943, when President Franklin D. Roosevelt proclaimed Jackson Hole National Monument in Wyoming. 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.
The most substantial use of the proclamation authority came in 1978, when President Jimmy Carter 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 Misty Fjords and Admiralty Island National Monuments in the U.S. Forest Service and Becharof and Yukon Flats National Monuments in the Fish and Wildlife Service, the first to be created outside of the National Park Service. The latter two became national wildlife refuges in 1980.
The proclamation authority was not used again anywhere until 1996, when President Bill Clinton proclaimed the Grand Staircase–Escalante National Monument in Utah. This was the first national monument managed by the 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. Most of the 16 national monuments created by President Clinton are managed not by the National Park Service, but by the Bureau of Land Management as part of the National Landscape Conservation System.
President George W. Bush created four marine national monuments in the Pacific Ocean, the largest in the system. They are the Papahānaumokuākea Marine National Monument, the Pacific Remote Islands Marine National Monument, the Marianas Marine National Monument, and the Rose Atoll Marine National Monument.They are managed by the Fish and Wildlife Service, with the National Oceanic and Atmospheric Administration overseeing the fisheries.
President Barack Obama significantly expanded two of them and added a fifth in the Atlantic Ocean.
On June 24, 2016, President Barack Obama designated the Stonewall Inn and surrounding areas in Greenwich Village, New York as the Stonewall National Monument, the first national monument commemorating the movement for LGBT rights in the United States.Obama's establishments included several others recognizing civil rights history, including the César E. Chávez, Belmont–Paul Women's Equality, Freedom Riders, and Birmingham Civil Rights National Monuments.
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.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.
Grand Canyon National Park, located in northwestern Arizona, is the 15th site in the United States to have been named as a national park. The park's central feature is the Grand Canyon, a gorge of the Colorado River, which is often considered one of the Wonders of the World. The park, which covers 1,217,262 acres of unincorporated area in Coconino and Mohave counties, received more than six million recreational visitors in 2017, which is the second highest count of all American national parks after Great Smoky Mountains National Park. The Grand Canyon was designated a World Heritage Site by UNESCO in 1979. The park celebrated its 100th anniversary on February 26, 2019.
The Grand Staircase–Escalante National Monument (GSENM) is a United States national monument protecting the Grand Staircase, the Kaiparowits Plateau, and the Canyons of the Escalante in southern Utah. It was established in 1996 by President Bill Clinton under the authority of the Antiquities Act with 1.7 million acres of land, later expanded to 1,880,461 acres (7,610 km2). In 2017, the monument's size was reduced by half in a succeeding presidential proclamation, and it was restored in 2021. The land is among the most remote in the country; it was the last to be mapped in the contiguous United States.
The Antiquities Act of 1906, is an act that was passed by the United States Congress and signed into law by Theodore Roosevelt on June 8, 1906. This law gives the President of the United States the authority to, by presidential proclamation, create national monuments from federal lands to protect significant natural, cultural, or scientific features. The Act has been used more than a hundred times since its passage.
The Papahānaumokuākea Marine National Monument (PMNM) is a World Heritage listed U.S. National Monument encompassing 583,000 square miles (1,510,000 km2) of ocean waters, including ten islands and atolls of the Northwestern Hawaiian Islands. Created in June 2006 with 140,000 square miles (360,000 km2), it was expanded in August 2016 by moving its border to the limit of the exclusive economic zone, making it one of the world's largest protected areas. It is internationally known for its cultural and natural values as follows:
The area has deep cosmological and traditional significance for living Native Hawaiian culture, as an ancestral environment, as an embodiment of the Hawaiian concept of kinship between people and the natural world, and as the place where it is believed that life originates and to where the spirits return after death. On two of the islands, Nihoa and Mokumanamana, there are archaeological remains relating to pre-European settlement and use. Much of the monument is made up of pelagic and deepwater habitats, with notable features such as seamounts and submerged banks, extensive coral reefs and lagoons.
The Wilderness Society is an American non-profit land conservation organization that is dedicated to protecting natural areas and federal public lands in the United States. They advocate for the designation of federal wilderness areas and other protective designations, such as for national monuments. They support balanced uses of public lands, and advocate for federal politicians to enact various land conservation and balanced land use proposals. The Wilderness Society also engages in a number of ancillary activities, including education and outreach, and hosts one of the most valuable collections of Ansel Adams photographs at their headquarters in Washington, D.C.
Escalante National Monument was proposed by Secretary of the Interior Harold Ickes in the 1930s as a unit of the U.S. National Park Service in the canyonlands of south central Utah. Centering on the canyons of the Escalante River, the proposed monument encompassed portions of present-day Canyonlands and Capitol Reef national parks, Natural Bridges and Grand Staircase-Escalante national monuments and Glen Canyon National Recreation Area. The proposed national monument was to encompass about 4,500,000 acres (1,800,000 ha). The Second World War interrupted Ickes initiative, which had encountered resistance from Utah politicians.
Since 1872 the United States National Park System has grown from a single, public reservation called Yellowstone National Park to include 430 natural, historical, recreational, and cultural areas throughout the United States, its territories, and island possessions. These areas include National Parks, National Monuments, National Memorials, National Military Parks, National Historic Sites, National Parkways, National Recreation Areas, National Seashores, National Scenic Riverways, and National Scenic Trails.
The San Gabriel Mountains National Monument is a United States National Monument managed by the U.S. Forest Service, which encompasses parts of the Angeles National Forest and the San Bernardino National Forest in California. On October 10, 2014, President Barack Obama used his authority under the Antiquities Act to create the new monument, protecting 346,177 acres of public lands in the San Gabriel Mountains of the Transverse Ranges. The effort to protect the San Gabriel Mountains began more than a century earlier, in 1891 with another U.S. President, Benjamin Harrison, the 23rd president, using a congressional act, to designate and delineate the first federal protection in the United States of forested lands, using the same mountain range name, as the San Gabriel Timberland Reserve. Two earlier California conservationists, Abbot Kinney and John Muir, influenced President Benjamin Harrison.
Browns Canyon National Monument is a 21,586 acres (87 km2) national monument in Chaffee County, Colorado, that was designated as such by President Barack Obama under the Antiquities Act on February 19, 2015. The site will be centered along the Arkansas River between Buena Vista and Salida. Browns Canyon is the most popular destination for whitewater rafting in the country, and is also known for its fishing and hiking. The monument will provide habitat protection for bighorn sheep, peregrine falcons, elk, and golden eagles.
The Northeast Canyons and Seamounts Marine National Monument is a marine national monument of the United States off the coast of New England, on the seaward edge of Georges Bank. It was created by President Barack Obama on September 15, 2016 as the first U.S. marine national monument in the Atlantic Ocean.
Bears Ears National Monument is a United States national monument located in San Juan County in southeastern Utah, established by President Barack Obama by presidential proclamation on December 28, 2016. The monument protects 1,351,849 acres of public land surrounding the Bears Ears—a pair of buttes—and the Indian Creek corridor rock climbing area. The Native American names for the buttes have the same meaning in each of the languages represented in the region. The names are listed in the presidential proclamation as "Hoon’Naqvut, Shash Jáa [sic], Kwiyaghatʉ Nükavachi/Kwiyagatu Nukavachi, Ansh An Lashokdiwe"—all four mean "Bears Ears".
Gold Butte National Monument is a United States national monument located in Clark County, Nevada, northeast of Las Vegas and south of Mesquite and Bunkerville. The monument protects nearly 300,000 acres of desert landscapes featuring a wide array of natural and cultural resources, including rock art, sandstone towers, and important wildlife habitat for species including the Mojave Desert tortoise, bighorn sheep, and mountain lion. The area also protects historic ranching and mining sites such as the ghost town of Gold Butte, although little but mine openings, cement foundations, and a few pieces of rusting equipment remains. The monument is managed by the Bureau of Land Management.
The Marine Policy of the Barack Obama administration comprises several significant environmental policy decisions for the oceans made during his two terms in office from 2009 to 2017. By executive action, President Obama increased fourfold the amount of protected marine space in waters under United States control, setting an important precedent for global ocean conservation. Using the U.S. president's authority under the Antiquities Act of 1906, he expanded to 200 nautical miles the seaward limits of Papahānaumokuākea Marine National Monument in Hawaiʻi and the Pacific Remote Islands Marine National Monument around the U.S. island possessions in the Central Pacific. In the Atlantic, President Obama created the Northeast Canyons and Seamounts Marine National Monument, the first marine monument in the U.S. exclusive economic zone (EEZ) in the Atlantic.
Executive Order 13792, entitled "Review of Designations Under the Antiquities Act," is an executive order issued by US President Donald Trump on April 26, 2017, that directed the Secretary of the Interior to review designations of national monuments made since 1996. The order applies to all new monuments greater than 100,000 acres in size and monuments that were expanded by at least 100,000 acres. Twenty-two land monuments and five marine monuments that were created by the administrations of Bill Clinton, George W. Bush, and Barack Obama were subject to review.
Massachusetts Lobstermen's Association v. Ross is a United States District Court case in the District of Columbia in which the court determined whether or not a President may establish a marine national monument, the Northeast Canyons and Seamounts Marine National Monument, under the authority of the Antiquities Act of 1906. The case represents the first time that the President's authority to create an offshore marine monument under the Act was directly challenged in court. While the District Court upheld the President's authority to designate the monument under the authority bestowed by the Antiquities Act, the case was appealed to the D.C. Circuit and awaits further judicial review.
On March 15, 1943, Franklin D. Roosevelt signed Presidential Proclamation 2578 establishing a large swath of land east of the Teton National Park as a national monument. The area of land covered 221,610 acres. The majority of the land was National Forest, but 32,117 acres of the monument were donated by John D. Rockefeller, Jr., and 17,000 acres were privately owned ranches. This proclamation incited a controversy in Teton County that caused immediate pushback from western congressmen who saw the act as a violation of state sovereignty.
