Every pin on this map is a piece of American history the current administration has flagged for removal. These are real exhibits, signs, and publications from our national parks. They are historically accurate and now targeted for censorship. Click any marker to learn more about the history and why it matters.
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.
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.
A federal appeals court hearing on June 2 put the President’s House slavery exhibit removal at the center of the constitutional fight over federal control of historical narrative, just one month before Philadelphia hosts 1.5 million visitors for 250th anniversary celebrations on July 4. Before the Third Circuit, Justice Department attorneys asserted the National Park Service has unfettered discretion over exhibit content—even suggesting the government could eliminate any reference to slavery entirely—while city and advocacy attorneys defended the February lower court order mandating full restoration. The case turns on whether a cooperative agreement between the city and NPS requires federal approval before changes, with the administration arguing it donated the 2010 exhibit outright and retains absolute interpretive authority. The timing escalates the stakes: the site commemorating where George Washington enslaved nine people now sits dark as the nation prepares its largest patriotic gathering in decades.
The Philadelphia clash arrives amid broader evidence of the administration’s interpretive reach. Analysis of public comments released by the Sierra Club—which is pursuing a separate lawsuit to access internal records—found only a handful supporting removal efforts, undermining claims of grassroots demand for exhibit changes. The comments were solicited under the review process that produced the leaked database published by the Washington Post, which documented hundreds of displays flagged under Executive Order 14253. The Third Circuit’s ruling will determine not only whether one city can resist federal exhibit dismantling through contractual leverage, but whether courts will impose any limits on the administration’s claim of absolute curatorial power across the 423-unit park system—a precedent with implications for every site from Muir Woods to Fort Sumter.
