Mammoth Cave: The Longest Known Cave System on Earth
Mammoth Cave National Park in Kentucky protects more than 420 surveyed miles of passageways, by far the longest known cave system in the world, and surveyors keep finding more. In this episode: the sandstone cap rock that kept the cave from collapsing for ten million years, Stephen Bishop, the enslaved guide who mapped the cave by candlelight in the 1830s and 40s, and the failed 1840s tuberculosis experiment whose stone huts still stand deep underground today.
