# Antiquities Act Timeline The statute at the center of this timeline is three paragraphs long and has never had its core grant amended. What changes across 120 years is not the text but the answer to a single question: **is there anything a president may not do with it?** For most of that span the answer was supplied by custom and by an Attorney General's opinion from 1938, not by Congress or the courts. In 2025 the executive branch overruled itself, and in 2026 a federal appeals court answered the question for the first time — three weeks before the largest monument reduction in American history. Read alongside [[Antiquities Act]] for the doctrine and [[30x30 Conservation Initiative]] for the parallel conservation fight. --- ## 1889–1906: The Statute ### 1889 — Casa Grande Congress acts to protect the Casa Grande Ruin in Arizona Territory — the first federal protection of a prehistoric site, and the precedent every later account cites. It is ad hoc: there is no general preservation authority, only the Forest Reserve Act of 1891's withdrawal power and case-by-case appropriations, while commercial pothunting strips Mesa Verde, Chaco Canyon, and Casa Grande for the artifact trade. ### 1900 — The deadlock Rep. Jonathan P. Dolliver (R-IA) introduces the first bill authorizing **presidential** designation of prehistoric structures and natural formations. Rep. John Shafroth (D-CO) introduces a competing bill vesting the power in the **Secretary of the Interior**, limited to specified western states with a **320-acre maximum per monument**. Neither passes. The acreage cap dies with the Shafroth bill and is never revived. ### 1904–1906 — Hewett drafts the compromise Archaeologist **Edgar Lee Hewett**, working for the Archaeological Institute of America, surveys Southwestern ruins and drafts the bill that breaks the impasse. His decisive design choice is to vest the authority in the **President** — and to omit any acreage limit. ### June 8, 1906 — The Act is signed [[Theodore Roosevelt]] signs the Antiquities Act, 34 Stat. 225. Floor manager **Rep. John F. Lacey (R-Iowa)**, chairman of the House Committee on Public Lands, assures colleagues that the "smallest area compatible with the proper care and management of the objects to be protected" language will prevent extensive withdrawals, expressly contrasting the bill with the Forest Reserve Act's tens of millions of acres. *That floor assurance is now quoted in every modern monument case, by both sides.* --- ## 1906–1943: The Power Exceeds Its Promise Immediately ### September 1906 — Devils Tower Roosevelt proclaims Devils Tower, Wyoming, the first national monument — three months after signing the Act. ### January 1908 — Grand Canyon Roosevelt proclaims the Grand Canyon a national monument at more than 800,000 acres. Eighteen months after Lacey's assurance, the Act has been used for a withdrawal on the exact scale he promised it could not reach. Congress makes the Grand Canyon a national park in 1919. ### 1920 — *Cameron v. United States* The [[Supreme Court of the United States]] upholds the Grand Canyon monument against mining claimant Ralph Cameron, holding the canyon qualifies as an "object of unusual scientific interest." The holding that **natural features, not only man-made antiquities, are protectable** is the foundation of every large landscape monument since. Cited in every subsequent case. ### March 15, 1943 — Jackson Hole [[Franklin D. Roosevelt]] proclaims Jackson Hole National Monument, 221,610 acres, over intense Wyoming opposition. Congress passes a bill abolishing it; **FDR pocket-vetoes the bill**, then Congress refuses to appropriate any funds for the monument for seven years. ### 1945 — *Wyoming v. Franke* The federal district court in Wyoming declines to enjoin the Jackson Hole monument, holding the dispute essentially political and judicial review of the President's factual determination extremely limited — relief lies with Congress, not the courts. The court does suggest it could intervene against a palpable abuse, a door left open for eighty years. --- ## 1935–1980: Doctrine and the Two Carve-Outs ### 1935 — The Interior Solicitor's opinion Solicitor's Opinion M-27657 concludes that presidential authority to **modify** a monument exists. ### 1938 — Attorney General Cummings and Castle Pinckney Asked whether the President may **abolish** Castle Pinckney National Monument in South Carolina, Attorney General **Homer Cummings** concludes he may not: *"the grant of power to execute a trust … by no means implies the further power to undo it when it has been completed."* **This opinion governs executive-branch practice for eighty-seven years.** No president ever abolishes a monument. Presidents do reduce them — eighteen times before 2017. ### September 14, 1950 — The Wyoming exemption Truman signs the Jackson Hole settlement: the monument is folded into Grand Teton National Park, and the Act is amended to provide that **no national monument may be established or extended in Wyoming without express congressional authorization**. Now 54 U.S.C. § 320301(d). The first and only outright geographic prohibition. ### 1961–1963 — Bandelier [[John F. Kennedy]] shrinks Bandelier National Monument by roughly 4,000 acres — the most-cited pre-2017 reduction precedent, and the practice on which the entire "presidents have always done this" argument rests. ### 1969–1993 — Three presidents decline [[Richard Nixon]], [[Ronald Reagan]], and [[George H.W. Bush]] designate **zero** national monuments — the only three presidents since 1906 never to use the Act. Litigation over the statute essentially ceases for a quarter century. ### December 1, 1978 — Carter's Alaska proclamations [[Jimmy Carter]], with Alaska lands legislation deadlocked in Congress, proclaims **17 national monuments totaling roughly 56 million acres in a single day** — the largest use of the Act in its history by an order of magnitude. Alaska's reaction is immediate and bitter. ### November 1978 — *State of Alaska v. Carter* The federal district court in Alaska denies an injunction, holding that **the President is not a "federal agency"** and is therefore not subject to the [[National Environmental Policy Act]]'s impact-statement requirement when exercising Antiquities Act authority. Combined with later holdings that proclamations are not reviewable under the [[Administrative Procedure Act]], this leaves the power almost entirely outside the ordinary machinery of administrative law. ### December 2, 1980 — ANILCA The Alaska National Interest Lands Conservation Act supersedes Carter's proclamations by folding the lands into a statutory scheme creating over 100 million acres of conservation units — and adds a prospective limit: any future executive withdrawal exceeding **5,000 acres in the aggregate** in Alaska requires congressional notice and **terminates within one year absent a joint resolution of approval**. *Wyoming and Alaska remain the only two limits Congress has ever enacted.* --- ## 1996–2016: Revival, and the Modern Grievance ### September 1996 — Grand Staircase-Escalante [[Bill Clinton]] proclaims [[Grand Staircase-Escalante National Monument]], roughly 1.7 million acres in southern Utah — announcing it from the rim of the Grand Canyon, in Arizona, because the reaction in Utah is expected to be severe. The Kaiparowits Plateau, holding one of the largest undeveloped coal deposits in the country, is inside the boundary. This designation revives both the Act and the controversy, and becomes the founding grievance of modern Utah public-lands politics. ### 2000–January 2001 — The Clinton wave Clinton proclaims 19 new monuments and enlarges 3 more, including Giant Sequoia, Grand Canyon-Parashant, Canyons of the Ancients, Cascade-Siskiyou, Hanford Reach, Ironwood Forest, and Sonoran Desert. ### October 18, 2002 — The D.C. Circuit forecloses the "smallest area" claim Two decisions issued the same day by the same panel: - ***Mountain States Legal Foundation v. Bush*** — challenge to six Clinton proclamations dismissed; the [[Mountain States Legal Foundation]] complaint "failed to present any factual allegation sufficient to warrant review." - ***Tulare County v. Bush*** — challenge to Giant Sequoia dismissed on all nine counts. Holdings: a proclamation need not describe protected objects in detail; **ecosystems and scenic vistas qualify as protectable "objects"**; the Act is not an unconstitutional delegation; presidential action is not reviewable under the APA. Cert denied 2003. The "smallest area" claims fail not because the clause is unreviewable but because plaintiffs plead legal conclusions instead of facts. That distinction sits dormant for twenty-four years. ### 2006–2016 — The marine era [[George W. Bush]] proclaims [[Papahānaumokuākea Marine National Monument]] in the Northwestern Hawaiian Islands (June 15, 2006), then the largest marine protected area on Earth, followed by the [[Pacific Islands Heritage Marine National Monument]], Marianas Trench, and Rose Atoll in January 2009. [[Barack Obama]] quadruples Papahānaumokuākea in August 2016 to roughly 582,578 square miles and proclaims the Atlantic's first marine monument, **Northeast Canyons and Seamounts**, in September 2016. *These Pacific designations will turn out to constitute 96–99 percent of all "protected" US ocean — the fact that later makes the marine half of [[30x30 Conservation Initiative]] a bookkeeping exercise.* ### December 28, 2016 — Bears Ears Obama proclaims [[Bears Ears National Monument]], roughly 1,351,849 acres — the first monument proposed by a coalition of sovereign tribal nations (Navajo, Hopi, Ute Mountain Ute, Ute Indian Tribe, Zuni), with a formal inter-tribal management commission written into the proclamation. Obama's total reaches 29 new monuments plus 5 enlargements. --- ## 2017–2021: The First Reduction Fight ### April 26, 2017 — Executive Order 13792 [[Donald Trump]] orders [[Ryan Zinke]] to review every designation since January 1, 1996 exceeding 100,000 acres. Twenty-seven monuments reviewed; **2.4 million public comments** filed. Zinke's report recommends boundary modifications, three new monuments, and legislation requiring state, local, and tribal consultation before designation. ### December 4, 2017 — The proclamations - **Proclamation 9681** cuts Bears Ears to **228,794 acres** — roughly **85 percent**. - **Proclamation 9682** cuts Grand Staircase-Escalante to **1,003,863 acres** — roughly **47 percent**. ### December 2017 — The suits *Hopi Tribe v. Trump*, *Wilderness Society v. Trump*, and *NRDC v. Trump* are filed in D.D.C. within days. In November 2018, 118 members of Congress file amicus briefs. **The Justice Department's litigating position concedes that a president cannot revoke a monument**, arguing only for a power to reduce. The merits are never reached. ### October 26, 2018 — Camp Nelson Trump proclaims Camp Nelson National Monument in Kentucky — his only Antiquities Act designation in either term. ### March 22, 2021 — The Roberts statement The Supreme Court denies certiorari in *Massachusetts Lobstermen's Association v. Raimondo*, a challenge to the Northeast Canyons marine monument. **Chief Justice [[John Roberts]] issues a statement respecting the denial**, writing that the "smallest area compatible" restriction *"has ceased to pose any meaningful restraint"* and that a statute authorizing designation of "landmarks," "structures," and "objects" has been *"transformed into a power without any discernible limit."* He notes the monument covers about 5,000 square miles of seabed — "about the size of Connecticut." He agrees with denial only because no court of appeals has squarely addressed the question and the record is inadequate. It reads unmistakably as an invitation. ### October 8, 2021 — Restoration [[Joe Biden]] issues Proclamations 10285 and 10286, restoring Bears Ears to roughly 1.36 million acres and Grand Staircase-Escalante to roughly 1.87 million. The 2017 suits are stayed and effectively mooted — the reduction question left undecided. ### 2022 — Utah sues the restoration Utah, Garfield County, and Kane County file *Garfield County v. Biden* and *Dalton v. Biden* in federal district court in Utah, challenging the restorations. --- ## 2022–2025: Biden's Designations and the Legal Reversal ### October 2022 – January 2025 — The Biden wave Camp Hale–Continental Divide, Colorado (October 2022); Avi Kwa Ame, Nevada (March 2023); **Baaj Nwaavjo I'tah Kukveni – Ancestral Footprints of the Grand Canyon**, Arizona (August 2023); and on **January 7, 2025**, in the administration's final days, **Chuckwalla** and **Sáttítla Highlands** in California, roughly 848,000 acres combined. ### August 11, 2023 — *Garfield County* dismissed Judge David Nuffer dismisses Utah's challenge with prejudice: no waiver of sovereign immunity; the President is not an "agency" under the APA; plaintiffs allege misuse of authority rather than absence of it, so the ultra vires exception does not apply. Utah appeals to the Tenth Circuit that October. ### January 20, 2025 — EO 14008 revoked [[Executive Order 14154]], "Unleashing American Energy," revokes [[Executive Order 14008]] in full at Section 4(a)(iii), executing the instruction in [[William Perry Pendley]]'s [[Project 2025]] Interior chapter. See [[30x30 Conservation Initiative]]. ### February 3, 2025 — Secretary's Order 3418 Interior Secretary [[Doug Burgum]] directs the department to review and "as appropriate, revise all withdrawn public lands," **expressly naming national monuments under 54 U.S.C. § 320301**. The review is conducted internally, without the public comment process Zinke ran in 2017. ### March 14–15, 2025 — The vanishing fact sheet A White House fact sheet states that Trump is *"terminating proclamations declaring nearly a million acres constitute new national monuments"* — language pointing at Chuckwalla and Sáttítla Highlands. **The language is deleted from the page within a day.** No monument is rescinded. Both remain designated as of August 2026. ### May 27, 2025 — OLC overrules 1938 The [[Office of Legal Counsel]] issues *Revocation of Prior Monument Designations*, addressed to the Counsel to the President. It concludes that a president may alter a prior declaration **including by eliminating the land reservation entirely**, by determining that the identified objects *"never were or no longer are deserving of the Act's protections"* — treating the protected **object**, not the land parcel, as the monument. Of the 1938 Castle Pinckney opinion: it *"was incorrect, and that opinion can no longer be relied upon."* Eighty-seven years of executive-branch doctrine ends in a fifty-page memorandum. Publicly reported June 10–11, 2025. --- ### April 2025 – June 2026 — The marine front opens a third mechanism Running in parallel to the Utah fight, and using a legal theory the Tenth Circuit case never touches. **April 17, 2025 — Proclamation 10918**, "Unleashing American Commercial Fishing in the Pacific," opens the 50-to-200-nautical-mile bands of the [[Pacific Islands Heritage Marine National Monument]] to US-flagged commercial fishing — roughly 310,000 square nautical miles. The same day, Executive Order 14276 directs Commerce and Interior to review every marine monument and recommend which to open. **This is not a reduction.** The boundaries are untouched. What the proclamation amends is the *management regime* — the clauses directing the Secretaries to impose prohibitions — on a finding that existing fisheries statutes make monument protections unnecessary. It is neither revocation nor diminishment, and it **predates the OLC opinion by five and a half weeks**, so it was never blessed by it. **August 8, 2025** — in *Kāpaʻa v. Trump*, a federal court in Hawaiʻi **vacates the National Marine Fisheries Service letter** implementing the proclamation, because NMFS bypassed Magnuson-Stevens notice-and-comment rulemaking. The government concedes. But the court rules only on the agency's procedure; **the proclamation's own legality is left undecided**, with a non-jury trial reported for December 7, 2026. **June 11, 2026 — Proclamation 11035** reopens the Mau and Hoʻomalu zones of [[Papahānaumokuākea Marine National Monument]], the Mariana Trench Islands Unit, and the waters 12–50 nm around Rose Atoll — roughly 477,000 square miles. Two days before, in the Atlantic, NOAA had used the APA's "good cause" exemption to rescind the Northeast Canyons fishing restrictions without public comment — the precise shortcut the Hawaiʻi court rejected in 2025, and now itself under challenge in D.D.C. **What blocks it anyway:** Papahānaumokuākea became a **national marine sanctuary effective March 3, 2025** under regulations finalized in the Biden administration's last days. Sanctuary rules independently prohibit commercial fishing and were issued under the National Marine Sanctuaries Act — a proclamation modifying the *monument* cannot repeal them. As of August 2026, **no commercial fishing has resumed in any Pacific monument.** *The significance: these five monuments hold 96–99 percent of all fully or highly protected US ocean. The marine front is where the Act's reach is largest and its legal test is newest.* --- ## 2026: The Question Answered, and the Cut ### April 1, 2026 — *Arizona State Legislature v. Biden* The Ninth Circuit affirms dismissal of the challenge to Baaj Nwaavjo I'tah Kukveni for lack of standing: lost uranium tax revenue is speculative, the state legislature suffered no concrete injury, and the water claim rests on restrictions not in the proclamation. The monument stands. ### March–June 2026 — The CRA route fails Utah's delegation pursues a [[Congressional Review Act]] resolution against BLM's 2024 Grand Staircase-Escalante management plan, on the contested theory that a resource management plan is a "rule." Six southwestern tribes form the Grand Staircase-Escalante Inter-Tribal Coalition in response (March 25). **The resolution fails around June 12**, when the 60-legislative-day fast-track window closes without a Senate vote. ### June 23, 2026 — The Tenth Circuit answers Roberts ***Garfield County v. Trump***, decided 2–1. The Tenth Circuit **reverses in part and holds that sovereign immunity does not bar ultra vires review of Antiquities Act proclamations.** Judge Carson's majority distinguishes presidential *discretion* (unreviewable) from presidential *authority* (reviewable): subsection (b)'s "shall be confined to the smallest area compatible" is **mandatory language imposing a judicially enforceable constraint**. *"When the President exceeds statutory limits placed on his power, his actions are ultra vires and enjoy no immunity from suit."* Judge Federico dissents. Remanded for the district court to interpret the statutory scope of "objects of historic or scientific interest." **The first federal appellate holding that the "smallest area" clause has teeth** — and a live split with the D.C. Circuit's *Tulare County* line. Utah won it in order to attack a Democratic restoration. ### July 13, 2026 — The largest reduction in the Act's history Three weeks after the Tenth Circuit ruling and one month after the CRA effort died, Trump signs two proclamations: | Monument | Proclamation | Prior acreage | Retained | Cut | |---|---|---|---|---| | [[Bears Ears National Monument]] | 11043 | ~1,360,000 | ~121,096 | **~91.1%** | | [[Grand Staircase-Escalante National Monument]] | 11044 | ~1,870,000 | ~181,541 | **~90.3%** | Roughly **2.93 million acres removed**. The stated rationale applies the 2025 OLC theory directly: the prior designations violated "smallest area compatible"; sedimentary rock layers, petroglyphs "common throughout the American West," and landscape-scale biodiversity are not qualifying objects; other statutes already protect the resources; BLM lacks capacity to manage the acreage. The Bears Ears proclamation additionally invokes **critical minerals — silver, copper, uranium, vanadium — as a national-security justification**, a first for a monument reduction. Published July 17, 2026 at 91 FR 45169 and 91 FR 45179. Mineral entry on excluded lands opens **September 11, 2026**. ### July–August 2026 — The scramble Tribal nations (through the Native American Rights Fund) and conservation groups (through [[Earthjustice]]) announce intent to sue. Kimmerle Mining files seven claims in San Juan County on July 14; Craig Rosequist files two in Kane County on August 6. Earthjustice asks [[Bureau of Land Management]] to reject both as premature, since appropriation before the restoration date is unauthorized. **As of August 14, 2026, no complaint has been confirmed filed.** The Congressional Research Service publishes **R49048, *Presidential Authority Under the Antiquities Act***, on July 30 — the most current authoritative overview of a question that has been open since 1906 and urgent since May 2025. --- ## Open Questions Does the "smallest area compatible" clause constrain **reductions** as well as designations — and if it does, does the Tenth Circuit's remand hand the challengers of Proclamations 11043 and 11044 the same weapon Utah forged? Will the Supreme Court take the circuit split, and if [[John Roberts]] meant what he wrote in 2021, does he mean it symmetrically? Can an eighty-seven-year-old Attorney General opinion be discarded by a fifty-page OLC memorandum with no judicial test, and what else in the executive-branch canon becomes discardable on that precedent? What survives of the Bears Ears Inter-Tribal Commission — a co-management structure negotiated with sovereign nations — when the monument it governs loses 91 percent of its area? And does the ratchet ever stop: is there any equilibrium for a policy instrument that requires one signature to create and, now, one signature to erase? ## Connections This timeline is the public-lands branch of the [[Sagebrush Rebellion]] through-line, and it converges with nearly every other structure this vault tracks. The personnel pipeline — [[Mountain States Legal Foundation]] to [[James Watt]] to [[William Perry Pendley]] to the [[Project 2025]] Interior chapter — is the same movement-to-agency capture documented in the [[Federalist Society]]'s judicial program and traced in the [[Conservative Court Capture Timeline]]. The extraction economics beneath every boundary fight connect to the [[Climate Change Timeline]] and [[Energy Transition Politics]]. The county-resolution machinery deployed against monuments is the same machinery deployed against conservation goals in [[30x30 Conservation Initiative]], run by the same organization, [[American Stewards of Liberty]]. The deepest connection is doctrinal. The Antiquities Act is where [[Unitary Executive Theory]] meets its most permissive statute: a power delegated in three paragraphs, exercised without procedure, historically unreviewable, and now claimed to include the power to undo itself. Whatever the courts decide about "the smallest area compatible" will be about far more than Utah. ## See Also - [[Antiquities Act]] — the statute, the doctrine, and the current fight - [[Bears Ears National Monument]] — four boundaries in ten years - [[Grand Staircase-Escalante National Monument]] — the 1996 designation that started the modern grievance - [[30x30 Conservation Initiative]] — the parallel conservation program, killed by the same coalition - [[Sagebrush Rebellion]] — the movement organized against federal land retention - [[Bureau of Land Management]] — manager of most contested monument acreage - [[Office of Legal Counsel]] — author of the 2025 opinion that made the 2026 proclamations possible - [[Papahānaumokuākea Marine National Monument]] · [[Pacific Islands Heritage Marine National Monument]] — the marine front and its separate legal theory
