In this episode of The Atlas Obscura Podcast, listen as two hikers, a mother and son, trek through Michigan’s Isle Royale—the least-visited national park in the United States—to search for something they’d seen on Atlas Obscura: Moose Boulder. Except Moose Boulder probably doesn’t even exist.

Our podcast is an audio guide to the world’s wondrous, awe-inspiring, strange places. In under 15 minutes, we’ll take you to an incredible site, and along the way you’ll meet some fascinating people and hear their stories. Join us daily, Monday through Thursday, to explore a new wonder with cofounder Dylan Thuras and a neighborhood of Atlas Obscura reporters.
