National Monuments and the Antiquities Act
Released: 2018-11-30T00:00:00

Summary:
The Antiquities Act of 1906 (54 U.S.C. §§320301-320303) authorizes the President to proclaim national monuments on federal lands that contain historic landmarks, historic and prehistoric structures, or other objects of historic or scientific interest. The President is to reserve "the smallest area compatible with the proper care and management of the objects to be protected." The act was designed to protect federal lands and resources quickly. Presidents have proclaimed a total of 158 monuments, and also have enlarged, diminished, and changed the terms of monuments previously proclaimed by Presidents. Congress has modified many of these proclamations and has abolished some monuments. Congress also has created monuments under its own authority.
Presidential establishment of monuments sometimes has been contentious—for example, President Franklin D. Roosevelt's creation of the Jackson Hole National Monument in Wyoming (1943) and President Clinton's establishment of 19 monuments and expansion of 3 others (1996-2001). Debate over the President's authority to establish and modify national monuments has continued in light of more recent presidential action, namely President Obama's designation of 29 new monuments and enlargement of 5 others, and President Trump's designation of 1 monument and reduction and modification of the terms of 2 others.
Various issues regarding presidentially designated monuments have generated controversy, lawsuits, statutory changes, and legislative proposals to limit the President's authority. Some concerns have centered on the extent of the President's authority to establish and modify monuments, the size of the areas, the types of protected resources and the level of threats to these resources, the inclusion of nonfederal lands within monument boundaries, the selection of the managing agency, restrictions on land uses that may result, and the manner in which the monuments were created.
Most monument advocates favor the Antiquities Act in its present form. They believe that the act serves an important purpose in preserving resources for future generations and that the President needs continued authority to act promptly to protect valuable resources on federal lands from potential threats. They assert that the public has supported and courts have upheld designations by the President and that many past presidential designations that initially were controversial have come to be supported.
Given the recurring controversies over presidential monument proclamations, Congress has evaluated whether to abolish, limit, or retain unchanged the President's authority under the Antiquities Act. During recent Congresses, measures were considered to impose restrictions on presidential authority, including to limit the designation of monuments in particular locations and promote presidential creation of monuments in accordance with certain federal land management, public participation, and environmental laws. Other measures sought to change land uses within monuments or alter monument boundaries. Among other bills, some proposals would have barred the President from reducing or abolishing national monuments or increased funds for presidentially proclaimed monuments.

subsections: section_title: Introduction
paragraphs: The Antiquities Act of 1906 authorizes the President to proclaim national monuments on federal lands that contain "historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest." The President is to reserve "the smallest area compatible with the proper care and management of the objects to be protected." Congress subsequently limited the President's authority by requiring congressional authorization for extensions or establishment of monuments in Wyoming, and by making withdrawals in Alaska exceeding 5,000 acres subject to congressional approval. 
The Antiquities Act was a response to concerns over theft from and destruction of archaeological sites and was designed to provide an expeditious means to protect federal lands and resources. President Theodore Roosevelt used the authority in 1906 to establish Devils Tower in Wyoming as the first national monument. Seventeen of the 20 Presidents since 1906 created 158 monuments, including the Grand Canyon, Grand Teton, Zion, Olympic, Statue of Liberty, and Chesapeake and Ohio Canal. President Franklin D. Roosevelt used his authority the most often (36 times), and President Obama proclaimed the most monument acreage (about 554 million, primarily in two expanded marine monuments). For a comparison of President Obama's and President Franklin D. Roosevelt's use of the monument authority, see Appendix A . For information on the use of the authority by all Presidents since 1906, see Appendix B . 
section_title: Monument Issues and Controversies
paragraphs: Presidential establishment of national monuments under the Antiquities Act of 1906 has protected sites with historic and scientific values, but it has also been contentious. Various issues regarding presidentially created monuments have generated controversy, lawsuits, statutory changes, and legislative proposals to limit the President's authority. Concerns have centered on the extent of the President's authority to establish and modify monuments, the size of the areas, the types of protected resources and the level of threats to the areas, the inclusion of nonfederal lands within monument boundaries, and the selection of the managing agency. Another issue has been restrictions that may result on land uses, both extractive (e.g., mining) and recreational (e.g., off-road vehicle use). Still another focus is the manner in which the monuments were created. This includes the lack of a requirement for state or congressional approval prior to presidential monument proclamations, and a perceived lack of consistency between the Antiquities Act and the policies established in other laws pertaining to land withdrawals, environmental reviews, and public participation. 
Most monument advocates favor the Antiquities Act in its present form. They believe that the act serves an important purpose in preserving resources for future generations. They maintain that Presidents of both parties have used the authority for over a century to protect valuable federal lands and resources expeditiously, and they defend the President's ability to take prompt action to protect resources that may be vulnerable to looting, vandalism, commercial development, and other permanent changes. They contend that significant segments of the public support monument designations for the protections they afford and the recreational, preservation, and economic benefits that such designations sometimes bring. They further assert that previous Congresses that focused on this issue were correct in not repealing the Antiquities Act, and that courts have supported presidential actions.
Litigation and legislation related to the law have been pursued throughout its history. To give one historical example, displeasure with President Franklin D. Roosevelt's proclaiming of the Jackson Hole National Monument in Wyoming in 1943 (which became Grand Teton National Park) prompted litigation on the extent of presidential authority under the Antiquities Act, and led to a 1950 law prohibiting future establishment of national monuments in Wyoming unless Congress made the designation. As another example, President Carter's establishment of monuments in Alaska in 1978 also was challenged in the courts and led to a statutory requirement for congressional approval of land withdrawals in Alaska larger than 5,000 acres. President Clinton's proclamation of the Grand Staircase-Escalante National Monument in 1996 triggered several lawsuits, a law authorizing land exchanges, a law altering the borders of the monument, and proposals to amend or revoke presidential authority under the Antiquities Act.
Initial opposition to some monument designations has turned to support over time. Some controversial monuments later were redesignated as national parks by Congress and today are generally considered popular parks with substantial economic benefit to the surrounding communities. For instance, the Grand Canyon National Monument, proclaimed in 1908 and the subject of a legal challenge, is now a world-famous national park. 
The more recent application of national monument authority by President Obama and President Trump has continued to foster debate among some Members of Congress, state and local officials, user groups, and others. President Obama issued 34 monument proclamations, including designation of 29 new monuments and enlargement of 5 existing monuments. President Trump has issued three monument proclamations as of November 28, 2018, including one to designate a monument and two to reduce monument sizes and alter their terms and conditions. The actions of both Presidents led to lawsuits challenging the authority of the President and appeared to spur legislative proposals to limit the President's authority to create monuments, establish a process for input into monument decisions, and legislatively-establish national monuments, among other measures.
subsections: section_title: Modification of Monuments
paragraphs: The Antiquities Act does not expressly authorize the President to modify or abolish national monuments established by earlier presidential proclamation. This has contributed to uncertainty and debate over the extent of the President's authority in these areas, and scholars and others have reached different conclusions. 
No President has abolished a national monument. In contrast, throughout the history of the Antiquities Act, Presidents have modified national monuments established by earlier presidential proclamation. Such modifications included enlargement and/or diminishment of monument boundaries, by different amounts and percentages of the original monument acreage. As examples, four Presidents enlarged the Muir Woods National Monument following its establishment in 1908, and three Presidents diminished Mount Olympus National Monument following its establishment in 1909. 
Monuments have been modified in ways other than in size. Presidents have changed the terms and conditions of monument proclamations, although relatively infrequently. As an example, in 1936, President Franklin D. Roosevelt modified the Katmai National Monument to make the reservations in the earlier proclamations subject to valid existing "claims," since maintained. More recently, President Trump modified provisions of two Utah monuments—the Bears Ears National Monument and the Grand Staircase-Escalante National Monument. In general, monument proclamations have become more detailed and specific over time, making the question of potential changes to terms and conditions possibly more relevant. For instance, President Obama's 2016 proclamation establishing the Northeast Canyons and Seamounts Marine National Monument contained several paragraphs of management provisions and a number of prohibited and regulated activities. 
Congress has authority to create, modify, and abolish national monuments on federal lands, and has done so on numerous occasions under its constitutional authority to enact legislation regarding federal lands. This authority is not defined or limited by the provisions of the Antiquities Act. For instance, Congress could enact legislation to establish a national monument with more land uses than are typical for national monuments created by the President, such as allowing new commercial development, or with additional protections than are customary in presidential monuments. 
Congress has modified monuments, including those created by the President, for instance, by changing their boundaries. Congress has abolished some monuments outright and converted others into different protective designations, such as national parks. Approximately half of the current national parks were first designated as national monuments. 
section_title: Monument Size
paragraphs: In establishing a national monument, the President is required by the Antiquities Act to reserve "the smallest area compatible with the proper care and management of the objects to be protected." Monuments vary widely in size. While roughly half of the presidential monument proclamations involved fewer than 5,000 acres, they have ranged from less than 1 acre to about 283 million acres. 
More of the larger monuments have been created over the past half century, in Alaska and in marine areas, among other locations. However, there are examples of relatively large monument proclamations throughout the history of the Antiquities Act, including Katmai, established in 1918 with 1.1 million acres; Glacier Bay, created in 1925 with 1.4 million acres; many of the Alaska monuments proclaimed in 1978, the largest being Wrangell-St. Elias, with nearly 11 million acres; and Grand Staircase-Escalante, established in 1996 with 1.7 million acres. President George W. Bush established large marine monuments, namely the Papahanaumokuakea Marine National Monument (which includes the Northwestern Hawaiian Islands), with approximately 89.5 million acres; the Marianas Trench Marine National Monument, with 60.9 million acres; the Pacific Remote Islands Marine National Monument, with 55.6 million acres; and the Rose Atoll Marine National Monument, with 8.6 million acres. At the time, the George W. Bush Administration claimed that the latter three areas formed the largest protected ocean area in the world. More recently, President Obama expanded the Pacific Remote Islands Marine National Monument in 2014 by 261.3 million acres and the Papahanaumokuakea Marine National Monument in 2016 by 283.4 million acres. 
Critics assert that large monuments violate the Antiquities Act, in that the President's authority regarding size was intended to be narrow and limited. They charge that Congress intended the act to protect specific items of interest, especially archaeological sites and the small areas surrounding them. They support this view with the legislative history of the act, in which proposals to limit a withdrawal to 320 or 640 acres were mentioned although not enacted. They contend that some of the monument designations were greater than needed to protect particular objects of value, and that the law was not intended to protect large swaths of land or ocean. 
Defenders observe that by not specifically capping the size of monument designations, the Antiquities Act gives the President discretion to determine the acreage necessary to ensure protection of the resources in question, which can be a particular archaeological site or larger features or resources. The Grand Canyon, for example, originally was a national monument measuring 0.8 million acres; President Theodore Roosevelt determined that this size was necessary to protect the "object" in question—the canyon. Defenders also note that after considering the issue in the early 1900s, Congress rejected proposals to restrict the President's authority to set the size of the withdrawal. Further, they assert that preserving objects of interest may require withdrawal of sizeable tracts of surrounding land to preserve the integrity of the objects and the interactions and relationships among them.
section_title: Establishment Criteria
paragraphs: Under the Antiquities Act, the President can establish monuments on federal land containing "historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest." Some proclamations have identified particular objects needing protection, while others have referred more generally to scenic, scientific, or educational features of interest.
Presidents sometimes have cited threats to resources (e.g., natural and cultural) to support establishing monuments, although imminent threat is not expressly required by the Antiquities Act. In his remarks designating the Grand Staircase-Escalante National Monument, for instance, President Clinton expressed concern about work underway for a large coal mining operation that, he asserted, could damage resources in the area. Sometimes the noted threats appear less immediate, as for the lands included in the Grand Canyon-Parashant Monument (proclaimed January 11, 2000) which "could be increasingly threatened by potential mineral development," according to the Clinton Administration. In other cases, threats were reported by the press or private organizations. For instance, the National Trust for Historic Preservation had identified the (subsequently proclaimed) President Lincoln and Soldiers' Home National Monument as one of the country's most endangered historic properties.
Presidential designation of monuments in the absence of immediate threats to resources troubles those who believe that the law is intended to protect objects that are in immediate peril of permanent harm. They contend that Presidents have established monuments to support environmental causes, limit development, and score political gains, among other reasons. Those who contest those charges note that the Antiquities Act lacks a requirement that objects be immediately threatened or endangered. Others cite the pervasive dangers of development and growth, looting, and vandalism as sufficient grounds for contemporary presidential action.
Some critics charge that, because the original purpose of the act was to protect specific objects, particularly objects of antiquity such as cliff dwellings, pueblos, and other archeological ruins (hence the name "Antiquities Act"), Presidents have used the act for excessively broad purposes. Among the broad purposes they cite are general conservation, recreation, scenic protection, or protection of living organisms. These purposes, they contend, are more appropriate for a national park or other designation established by Congress. Supporters of current presidential authority counter that the act does not limit the President to protecting ancient relics, and maintain that "other objects of historic or scientific interest" broadly grants considerable discretion to the President. 
section_title: Inclusion of Nonfederal Lands
paragraphs: The Antiquities Act initially states that it applies to lands owned or controlled by the federal government. However, it also states that, where the objects to be preserved are on privately owned lands, the property "may be relinquished to the Federal Government." Private and other nonfederal landowners have donated land under this provision, and presidents have subsequently designated national monuments that included the donated lands. Typically the monument designation occurs relatively quickly following the land donation. Land donation has occurred for both early and more recent presidential proclamations. As an early example, Secretary of the Interior James R. Garfield accepted the private donation of a redwood forest in California on December 31, 1907, and on January 9, 1908, President Theodore Roosevelt proclaimed the area the Muir Woods National Monument. More recently, former Secretary of the Interior Ken Salazar accepted donations leading to the establishment of some monuments by President Obama, including the César E. Chávez National Monument in California. 
It remains untested whether relinquishment of nonfederal lands must be voluntary (via donation, purchase, or exchange) or whether the President can convert private property to federal property through condemnation when establishing a national monument. To date, no presidential declaration of a monument has converted private property to federal property. 
In addition, in some cases, private or other nonfederal lands are contained within the outer boundaries of a proclaimed monument, although the ownership does not change by the monument designation. Such inclusions are sometimes a source of controversy. The Clinton Administration indicated that the monument designation does not apply to nonfederal lands; the then-Solicitor of the Department of the Interior (DOI) asserted this view in 1999 testimony before Congress. His testimony stated that the Antiquities Act applies only to federal lands and that monument designations cannot bring state or private lands into federal ownership. Some monument proclamations have stated that nonfederal lands will become part of the monument if the federal government acquires title to the lands.
Some, however, note that while private or state-owned lands are technically not part of the monument, development of such land located within monuments is difficult because certain types of development might be incompatible with the purposes for which the monument was created or constrained by management of the surrounding federal lands. Monument supporters note that if state or private landowners within a monument fear or experience difficulties, they can pursue land exchanges with the federal government. Some monument proclamations have authorized land exchanges to further the protective purposes of the monument. 
section_title: Monument Management
paragraphs: Although most monuments are managed by the National Park Service (NPS), both Congress and the President have created monuments managed by other agencies. For example, in 1996 President Clinton created the Grand Staircase-Escalante National Monument and assigned the Bureau of Land Management (BLM) its management. It was the first such area administered by BLM. Also, President George W. Bush selected the Fish and Wildlife Service (FWS), the National Oceanic and Atmospheric Administration in the Department of Commerce, and other agencies to manage marine monuments. As another example, on September 21, 2012, President Obama established the Chimney Rock National Monument with the Forest Service as the managing agency. In most cases, monuments created in recent decades have been assigned to be managed by the agency responsible for the area before the monument designation, although that was not always the case. For example, although the area proclaimed as the Minidoka Internment National Monument was managed by the Bureau of Reclamation before designation, the proclamation designating the monument changed management to the NPS.
The President's authority to choose a management agency other than NPS has been questioned. Before 1933, monuments were managed by different agencies, but in that year President Franklin D. Roosevelt consolidated management of national monuments in the NPS. Following the 1933 consolidation, it was not until 1978 that a presidentially created monument was managed by an agency other than the NPS. In 1978, two of the Alaska monuments created by President Carter were directed to be managed by the Forest Service, part of the U.S. Department of Agriculture, and two were managed by FWS. Assigning management to the Forest Service was controversial, and the two monuments were ultimately given statutory direction for Forest Service management. Others also assert that the authority of the President under the Antiquities Act carries with it discretion to choose the managing agency. 
Some critics contend that management by an agency other than the NPS is an illegal transfer of the current functions of the NPS. Others counter that establishing a new monument under another agency would not constitute a reorganization because management of current NPS units, and the general authority of the NPS to manage monuments, would be unaffected. Even if placing management authority under a department other than the DOI might constitute a reorganization, the President nevertheless might be able to move a function of the NPS to other DOI agencies under congressionally approved authority allowing transfers of functions within DOI. 
section_title: Effects on Land Use
paragraphs: The overriding management goal for all monuments is protection of the objects described in the proclamations. In general, existing uses of the land that are not precluded by the proclamations and do not conflict with the purposes of the monument may continue. Monument designation can limit or prohibit land uses, such as development or recreational uses. Limitations or prohibitions may be included in the proclamations themselves, accompanying Administration statements, management plans developed by the agencies to govern monument lands, agency policies, or other sources. Some use issues may not arise for particular monuments given their distinctive characteristics, for instance, their small size or water-based nature. 
A primary objection to national monuments is that the declaration changes the property from being federal land available for multiple uses to being a national monument with possible restricted uses. At least over the past 50 years, monument proclamations typically have had explicit protections for valid existing rights for land uses, but the extent to which designations may affect existing rights is not always clear. A common concern is that monument designation potentially could result in new constraints on development of existing mineral and energy leases, claims, and permits. Some fear that mineral exploration and extraction activities may have to adhere to a higher standard of environmental review, and may have a higher cost of mitigation, to ensure compatibility with the monument designation. 
Most monument proclamations since 1996 have barred new mineral leases, mining claims, prospecting or exploration activities, and oil, gas, and geothermal leases, subject to valid existing rights. This has been accomplished by language to withdraw the lands within the monuments from entry, location, selection, sale, leasing, or other disposition under public land laws, mining laws, and mineral and geothermal leasing laws. 
Another concern for some is whether commercial timber cutting will be restricted as a result of designation. For instance, President Clinton's proclamation of the Giant Sequoia National Monument (in 2000) expressly precluded future timber production, although certain then-current logging contracts could be completed. In many other cases, the proclamations have implied, through a general prohibition against removing any "feature" of the monuments, that timber cutting is precluded. Some assert that restrictions are needed to protect the environmental, scenic, and recreational attributes of forests preserved under the Antiquities Act. Logging supporters assert that forests can be used sustainably and that concerns raised by environmentalists as grounds for limiting commercial timber operations do not reflect modern forestry practices. 
Motorized and mechanized vehicles off-road are prohibited (except for emergency or authorized purposes) under the proclamations for many post-1996 monuments. Otherwise, the agency's management plan for a monument typically addresses whether to allow vehicular travel on designated routes or in designated areas or to close routes or areas to vehicular use in those monuments where such use is not expressly prohibited. In some areas that have become monuments, off-road vehicles have been allowed, at least in some places. 
Other concerns that some have raised included the possible effects of monument designation on hunting, fishing, and grazing. Some proclamations have restricted such activities to protect monument resources, and monument management plans may impose additional restrictions. For instance, proclamations for some marine monuments established by President George W. Bush restricted or prohibited commercial and recreational fishing. President Obama's expansion and establishment of marine national monuments appears to have enhanced focus on the potential effect of monument designations on fishing. In addition, monument designation provisions on grazing have been controversial in some cases, with some asserting that grazing has been unnecessarily curtailed and others claiming that grazing has not been sufficiently limited to prevent ecological damage. 
States and counties frequently have viewed restrictions on federal lands in their jurisdictions as threats to economic development. They maintain that local communities are hurt by the loss of jobs and tax revenues that results from prohibiting or restricting future mineral exploration, timber development, or other activities. Some contend that limitations on energy exploration could leave the United States more dependent on foreign oil. Advocates of creating monuments claim that economic benefits resulting from designation, including increased tourism, recreation, and attracting new businesses and residents, may exceed the benefits of traditional economic development. Others allege that the public interest value of continued environmental and resource protection outweighs any temporary economic benefit that could result from development. Some monument advocates support more restrictions on development. 
section_title: "Consistency" of Antiquities Act with NEPA and FLPMA
paragraphs: The Federal Land Policy and Management Act of 1976 (FLPMA) authorized the Secretary of the Interior to make certain land withdrawals under specified procedures. In enacting FLPMA, Congress also repealed much of the express and implied withdrawal authority previously granted to the President by several earlier laws. 
Critics of the Antiquities Act maintain that the act is inconsistent with FLPMA's intent of restoring control of public land withdrawals to Congress. They assert that Congress is the appropriate body to make and implement land withdrawal policy and that Congress intended to review and retain veto control over all executive withdrawals exceeding 5,000 acres. On the other hand, in enacting FLPMA, the 94 th Congress did not explicitly repeal or amend the Antiquities Act, despite extensive consideration of executive withdrawal authorities. Supporters of the Antiquities Act assert that Congress intended to retain presidential withdrawal authority under the Antiquities Act. 
Similarly, critics note that monuments have been proclaimed without the environmental studies required of agencies for "major federal actions" under the National Environmental Policy Act (NEPA), or the review of a public purpose and opportunity for public participation that FLPMA provides. However, neither NEPA nor FLPMA applies to the actions of a President (as opposed to an action of an agency), and the Antiquities Act is silent as to the procedures a President must follow to proclaim a new monument. Some want to add procedures for environmental review and public participation to the monument designation process so that significant withdrawals (with resulting effects on existing uses) would not be made without scientific evaluation, economic information, and public input. 
Others counter that such changes would impair the ability of the President to act quickly to protect objects and lands, thereby avoiding possible damage to the resources. They assert that participation requirements are not needed in law because Presidents typically consult with government officials and the public before establishing monuments. Some believe that NEPA requirements are unnecessary for monument designation because once monuments are created, detailed management plans are developed in accordance with NEPA.
section_title: President Obama's and President Trump's Monument Proclamations
paragraphs: President Obama designated 29 new national monuments in 17 states, the District of Columbia, and the Atlantic Ocean, off the coast of New England. They ranged in size from 0.12 acres to 1.6 million acres. President Obama also enlarged five monuments in California and Oregon, off the California Coast, and in marine areas. Enlargements ranged from 1,665 acres to 283.4 million acres. Brief information on each monument is included in Appendix C . 
The Obama Administration usually cited support for the establishment of the monuments—for instance, from government officials, businesses and local communities, or other stakeholders. Most of the areas that President Obama designated as monuments were first proposed for some sort of protective designation in legislation. In addition, some Members and segments of the public had advocated for additional monument designations in their states.
However, some federal and other governmental officials, communities, and stakeholders expressed opposition to monuments established by President Obama. Concerns centered on the process used to create monuments, particularly whether there was sufficient consultation with, and support from, Congress, local and state governments, residents of the affected areas, and the general public. Other concerns related to restrictions on land uses in new monuments, the frequency with which the President used his monument authority, and the size of some of the larger monuments, among other issues.
President Trump proclaimed one new monument in Kentucky—Camp Nelson—with 380 acres. The President also reduced and modified two monuments in Utah. The Grand Staircase-Escalante National Monument, established in 1996 by President Clinton, was reduced by about one million acres (about 47%), and the Bears Ears National Monument, established in 2016 by President Obama, was reduced by about 1.15 million acres (85%). These actions followed a 2017 review of certain national monuments by the Secretary of the Interior, at the direction of the President. The Secretary's final report recommended that Camp Nelson (and two other areas) be evaluated for national monument designation. The final report also recommended boundary changes and other modifications to the two Utah monuments, as well as changes to several other monuments. Brief information on each monument proclamation by President Trump is contained in Appendix C . 
section_title: Overview of Legislative Activity
paragraphs: Given the recurring controversies over presidential establishment and modification of national monuments, recent Congresses have evaluated whether to abolish, limit, or retain unchanged the President's authority to proclaim monuments under the Antiquities Act. Among the monument measures considered during recent Congresses were bills to impose restrictions on presidential authority, including to:
limit the size or duration of withdrawals; prohibit or restrict withdrawals in particular states or other locations (e.g., the exclusive economic zone); narrow the types of resources that could be protected; ban the inclusion of nonfederal land within monument boundaries; encourage public participation in the monument designation process; revoke the President's authority to designate monuments or require congressional and/or state approval of some or all monument designations; and promote presidential creation of monuments in accordance with certain federal land management laws and environmental laws. 
Other measures had a variety of additional purposes. They included changing land uses within monuments, imposing conditions on agency implementation of restrictions on monument use, addressing use of water within monument boundaries, and altering monument boundaries.
As previously noted, some Members and segments of the public have opposed legislation in recent Congresses that would restrict the President's authority to establish national monuments. (See the section above on " Monument Issues and Controversies .") Some of these supporters have introduced legislation to bar the President from reducing or abolishing national monuments. Other bills would increase funding for presidentially proclaimed monuments in general or dedicate funds to particular purposes, such as the development of management plans and recreational infrastructure.

This appendix provides a chronological list of President Obama's 34 monument proclamations under the Antiquities Act. For additional information on a particular monument, see the pertinent proclamation identified in the footnotes.
Fort Monroe National Monument in Virginia was designated on November 1, 2011. In establishing the 325-acre monument, the President stated that "Fort Monroe on Old Point Comfort in Virginia has a storied history in the defense of our Nation and the struggle for freedom." Fort Ord National Monument in California was designated on April 20, 2012. The purpose of the 14,651-acre Fort Ord National Monument is to maintain its historical and cultural significance, as well as attract tourists and recreationists and enhance the area's unique natural resources, according to the President. Chimney Rock National Monument in Colorado was designated on September 21, 2012. The President cited the "spiritual, historic, and scientific resources of great value and significance" in proclaiming the 4,726-acre monument. César E. Chávez National Monument in California was designated on October 8, 2012. The 10.5-acre monument "marks the extraordinary achievements and contributions to the history of the United States made by César Chávez and the farm worker movement that he led with great vision and fortitude," according to the President. First State National Monument in Delaware was designated on March 25, 2013. The 1,108 acres of the monument contain objects and areas of historic interest related to the settlement of Delaware and the role of Delaware as the first state to ratify the Constitution, according to the President. Charles Young Buffalo Soldiers National Monument in Ohio was designated on March 25, 2013. The 60-acre monument was established to commemorate the life and accomplishments of Colonel Charles Young, the highest-ranking African American commanding officer in the U.S. Army from 1894 until his death in 1922, the commander of a troop of Buffalo Soldiers, and the first African American superintendent of a national park, as described in the proclamation. Río Grande del Norte National Monument in New Mexico was designated on March 25, 2013. In proclaiming the monument, the President stated that protecting the 242,555-acre monument "will preserve its cultural, prehistoric, and historic legacy and maintain its diverse array of national and scientific resources, ensuring that the historic and scientific values of this area remain for the benefit of all Americans." San Juan Islands National Monument in Washington was designated on March 25, 2013. This 970-acre monument contains an archipelago of over 450 islands, rocks, and pinnacles in Washington's Puget Sound. According to the President, the area contains an "unmatched landscape," numerous wildlife species in diverse habitats, archaeological sites, and historic lighthouses and is a "refuge of scientific and historic treasures and a classroom for generations of Americans." Harriet Tubman–Underground Railroad National Monument in Maryland was designated on March 25, 2013. This 11,750-acre monument commemorates the life of Harriet Tubman, a leader of the Underground Railroad, and protects the landscape and historic features of the area in which she lived, worked, and later led enslaved African Americans to freedom, according to the proclamation. California Coastal National Monument was enlarged on March 11, 2014. President Obama added 1,665 onshore acres to this offshore monument, and named the expanded area the "Point Arena-Stornetta Unit." According to the proclamation, the area is of "significant scientific importance," and contains archeological and cultural sites and artifacts, a landscape shaped by "powerful geologic forces," and "spectacular wildlife," among other resources and values. Organ Mountains-Desert Peaks National Monument in New Mexico was designated on May 21, 2014. Among other attributes, the 496,330-acre monument includes mountain ranges and lowlands with archaeological resources; paleontological research areas; geologic features; historically significant areas; and diverse animals, vegetative communities, and ecosystems, according to the President. Pacific Remote Islands Marine National Monument was expanded on September 25, 2014, by approximately 261.3 million acres. The proclamation indicates that the expansion area includes opportunities for scientific study and research. It also identifies diverse species and habitats, such as deep-sea coral species, habitat and range for protected turtles, foraging habitat for seabird species, and an abundance of manta rays. San Gabriel Mountains National Monument in California was designated on October 10, 2014. In establishing the 346,177-acre monument, the President noted cultural, historic, and geologic features; recreational and scientific opportunities; and ecological diversity, among other distinctive elements. Browns Canyon National Monument in Colorado was designated on February 19, 2015. The 21,586-acre monument is described as an "iconic" landscape with diverse plants and wildlife and scientifically significant geological, ecological, riparian, cultural, and historic resources. It is also important for studying paleoecology, mineralogy, archaeology, and climate change, according to the President. Pullman National Monument in Illinois was designated on February 19, 2015.
