‘A sanitized view of America’: inside Trump’s campaign to erase US history from national parks

Critics say the Trump administration is trying to rewrite and whitewash history by removing and altering scores of signs on public lands

Jerry Bransford, a former US National Park Service (NPS) ranger, has always had a deep connection with the land he grew up on - and the land hundreds of feet below it. His great-great-grandfather, Materson Mat" Bransford, was one of the earliest explorers of Mammoth Cave in south-central Kentucky, the largest known cave system on the planet.

But for decades, Mat wasn't paid for his work. Enslavers rented him out for $100 a year to a man who wanted to turn the site into a tourist attraction - what would later become Mammoth Cave national park.
