Trump’s Executive Order Erases Brutal Truths from National Parks, Rewrites History in a Dangerous Revision

When you visit Grand Teton National Park this spring, don’t expect to see the full story behind the explorer Gustavus Cheyney Doane. Once, a plaque beneath his statue acknowledged both his role in creating the first national park and his leadership in a massacre of at least 173 Piegan Blackfeet members—a brutal act he boasted about. Now, that marker is gone, wiped away under a Trump administration executive order mandating a positive portrayal of American history in national parks.

This isn’t an isolated incident. Since President Trump’s March 2025 directive to the Department of the Interior to “take action” against content that “inappropriately disparages Americans past or living,” at least 45 changes have been made to National Park Service displays. Save Our Signs, an advocacy group tracking these removals, highlights how narratives about indigenous peoples, women’s contributions, and climate change are disappearing from public view.

At California’s Muir Woods National Monument, signs acknowledging Native American history and John Muir’s racist language have vanished. The message once conveyed—that indigenous people belong in these lands—is now erased, contributing to a false narrative that sidelines Native voices and experiences.

Climate change warnings have also been swept off the walls. Fort Sumter National Monument in South Carolina had a sign detailing how rising seas threaten its historic structures. The Interior Department replaced it, claiming the original was not “grounded in real science.” This move flies in the face of overwhelming scientific consensus and endangers public understanding of environmental threats.

Even revered founding fathers like George Mason are being sanitized. References to his slave ownership have been quietly removed, masking the contradictions inherent in America’s founding.

Tom Rodgers, a Blackfeet Nation member, calls this “killing them all over again,” referring to the victims of massacres like the one Doane led. His words capture the deep pain inflicted by erasing the darker chapters of history. “If you tell half the truth, you’ve told all the truth, and that in itself is a lie,” Rodgers says. “It’s Orwellian.”

This cultural purge comes as the nation approaches its 250th anniversary—a moment ripe for honest reflection. Instead, the Trump administration’s campaign threatens to whitewash history and suppress scientific facts, prompting lawsuits and protests. A coalition of conservationists has sued the Interior Department, accusing it of “mounting a sustained campaign to erase history and undermine science.” The case remains unresolved.

The Interior Department insists it is not removing history but presenting a “balanced, factual and appropriate” story. Yet internal National Park Service documents show hundreds of exhibits flagged for review, including books on slavery, films on mill workers, and displays on Japanese American internment. The criteria for removal are vague and dangerously subjective, often targeting any mention of injustice or discomfort.

This is not just a bureaucratic reshuffling. It is an authoritarian rewriting of the American story—one that prioritizes a sanitized myth over truth, erases the suffering of marginalized communities, and undermines urgent conversations about climate change. The Trump administration’s assault on historical accuracy in our national parks is a stark warning: when power controls the narrative, democracy and accountability suffer.
