Dr. Bob Smith’s interview on NPR’s Hear & Now

Here & Now’s Jeremy Hobson takes a tour of Yellowstone National Park’s geyser basin with a park ranger and a scientist who’s been studying the geology of the park for nearly 60 years.

Yellowstone is home to more geysers than any place on Earth, and researchers are still learning about how they work.
