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.
The Avenging the Ancestors Coalition will hold its 24th annual Slavery Commiseration on Tuesday, August 25 at 4 p.m. at the President’s House site on Independence Mall, marking the first commemoration since the Trump administration completed its replacement of exhibits that centered the nine enslaved people George Washington brought to Philadelphia. The annual event takes on new urgency following the July 15 overnight installation of more than 20 new panels that tell what organizers describe as a “broader story about slavery” without focusing on Washington’s direct culpability as an enslaver. The ceremony serves as both remembrance and resistance, reclaiming public space at a site where federal authorities now control the historical narrative under the Restoring Truth and Sanity to American History executive order.
The Philadelphia commemoration coincides with expanding grassroots documentation efforts nationwide, as former ranger Elizabeth Dalley’s organization America 433 conducts independent educational tours at parks where exhibits have been removed. A leaked database confirms that a Grand Teton exhibit was flagged for “non-conformance” on September 1, 2025, with the park acknowledging the sign’s removal in July—part of the 57 exhibits from 40 parks stripped before the now-vacated June 12 injunction. Dalley co-founded the preservation initiative after quitting the National Park Service in response to censorship directives, creating a parallel infrastructure to share histories the federal government has erased as litigation over the President’s House and other sites proceeds through appeals.
