In January 2026, the Trump administration ordered the National Park Service to remove dozens of signs, exhibits, and displays related to climate change, environmental science, and the historical mistreatment of Native Americans from some of America's most iconic national parks. The directive stems from Trump's executive order on “restoring truth and sanity to American history.”
Parks targeted include the Grand Canyon, Glacier National Park, Zion, Big Bend, Grand Teton, Little Bighorn Battlefield, and many more. At the Grand Canyon, signs describing how settlers “exploited land for mining and grazing” and how Native American tribes were pushed “off their land” for the park to be established were removed. At Glacier National Park, brochures showing glaciers retreating due to human-caused climate change were flagged for removal. At Little Bighorn, exhibit text describing the United States being “hungry for gold and land” and breaking promises to Native Americans was ordered changed or removed—as was text about how US-run boarding schools for Indigenous children “violently erased cultural identities and language.”
This is not “restoring truth”—it is erasing it. The displacement of Native Americans is documented historical fact. The retreat of glaciers is observable, measurable science. Removing these displays doesn't change what happened—it just ensures that millions of visitors to America's national parks learn a sanitized, dishonest version of the country's history. When a government starts removing inconvenient facts from public spaces, it's not protecting history—it's rewriting it.
