Why This Map Exists

×

This data belongs to the American people, who need to know what is being done to our National Parks. This administration is trying to use our public lands to erase history and undermine science.

Executive Order 14253 “Restoring Truth and Sanity to American History” and Secretary Order 3431 directed parks to censor any content “that inappropriately disparages Americans…or that emphasizes matters unrelated to the beauty, abundance, or grandeur” of natural features.
Why Are They Censoring Science and History?

Dismantling trusted sources of science and history makes their agenda of lies easier. Profiting from coal and oil is a lot easier if the impacts of fossil fuels are censored at sites like Muir Woods, Glacier, Acadia, and Everglades.

It’s easier to illegally detain people if we forget the true stories of Japanese-American incarceration in World War II, told at national park sites like Manzanar and Minidoka and Amache and Tule Lake and Honouliuli.

Propping up systemic racism is easier if you hide the evidence of the atrocities of chattel slavery, Jim Crow, and white nationalism at park sites like Medgar and Myrlie Evers Home, Cane River Creole, Rock Creek, and Independence Hall.

Most of all, they want to turn the American people against their national parks. They want to discredit the national parks and set the stage to privatize them.

Look at what they are censoring. Study it. Save it.
Find other people who care, and organize to fight back.
Build community around the science and history they want to erase.
And help us stop them.

Our Parks Need Your Voice

The Department of the Interior is removing and revising historical materials across the National Park System under Secretary's Order 3431. Congress has the power to stop this — but they need to hear from you.
443 park history entries with documented artifacts have been flagged, revised, or removed.
Momentum is building. On March 19, the NPCA and a coalition of historians, scientists, and park advocates filed for a preliminary injunction in federal court to halt the censorship. 53 House Democrats led by Rep. Jared Huffman are pushing to block funding for SO 3431. Add your voice to the pressure.

⚖️ Court Orders Park History Restored

Jul 16 – Jul 15, 2026 · 5 new developments
👁️ President's House Exhibit Replaced ⚖️ Third Circuit Ruling Executed ✊ Advocates Decry Whitewashing

Where the Fight Stands

The Trump administration completed its installation of replacement panels at Philadelphia’s President’s House Site overnight Tuesday, July 14 into Wednesday, July 15, removing exhibits that centered the nine people enslaved by George Washington and substituting displays that emphasize executive power and early American independence. Workers arrived at 5 a.m. Wednesday to install more than 20 new panels, according to representatives from the Avenging The Ancestors Coalition, who discovered the changes hours later. The new configuration relocates slavery content to the rear of the site while visitors entering from Market Street now encounter panels celebrating the presidential mansion’s architectural history. One replacement panel describes the enslaved individuals as “dynamic participants in the daily life of the family and the city,” language Michael Coard condemned as a complete whitewashing of American history. The installation occurred as South Philadelphia hosted MLB All-Star Game events, prompting Mayor Cherelle Parker to accuse the federal government of acting “under the cover of darkness.”

The overnight replacement marks the first completed content substitution at a major urban heritage site since the July 3 Third Circuit Court of Appeals ruling authorized exhibit changes while Philadelphia’s appeal proceeds. That decision—issued one day after Interior requested “immediate issuance” of the mandate—reversed lower court protections and cleared the National Park Service to resume installations at the President’s House and other flagged locations. The three-judge panel praised the replacement content as “full of historical context,” a characterization historians and civil rights advocates reject as sanitizing Washington’s culpability as an enslaver. With 57 exhibits from 40 parks already stripped before the now-vacated June 12 injunction, the Philadelphia installation demonstrates the administration’s capacity to execute permanent removals at sites nationwide under the Restoring Truth and Sanity to American History executive order. The completed work eliminates the city’s last physical leverage in ongoing litigation over whether the federal government can rewrite slavery narratives at founding-era sites as the 250th anniversary approaches.
