Going underground at Wind Cave National Park

What wonders are hiding underground? Producer Marc Sanchez finds out what it’s like to explore one of the biggest networks of caves in the world — and scientists are still discovering unmapped branches. Marc will show us the wonders hidden underground at this national park in South Dakota and how tricky it can be to brave uncharted territory with only a headlamp to light the way.
