Over a decade ago, an explorer conducting surveys at Grand Canyon National Park noticed what appeared to be an opening in a red rock cliff face high above him in the park’s remote backcountry. His team discovered a cave that appeared, by all accounts, to have been completely untouched by people. Researchers found a series of passageways with gypsum formations and a variety of wildlife, including thousands and thousands of mummified bats.
In episode 4 of the podcast, we talked with several experts about this remarkable cave and its ancient remains. Since then, researchers have returned and ventured into a second cave, even more difficult to explore than the first, and made more exciting discoveries.
This episode, host Jennifer Errick speaks Carol Chambers, professor of wildlife ecology at Northern Arizona University; Shawn Thomas, volunteer caver and bat expert; and Stephen Eginoire, photojournalist. We learn about the implications for science, the extreme lengths the team takes to preserve the cave, and profound feeling of being the first person to set foot in an unmapped place.
The Secret Lives of Parks is a production of the National Parks Conservation Association.
Episode 43, Return to the Bat Cave, was produced by Jennifer Errick, with help from Todd Christopher, Bev Stanton and Linda Coutant.
