We visit an underground oasis in Fresno, California, that’s a winding maze of rooms and passageways filled with lush citrus trees. All this week, we’re heading underground to discover the stories beneath our feet. Hosted by Simplecast, an AdsWizz company.

Under Our Feet: Upton Chamber

An audio guide to the world’s strange, incredible, and wondrous places. Co-founder Dylan Thuras and a neighborhood of Atlas Obscura reporters explore a new wonder every day, Monday through Thursday. In under 15 minutes, they’ll take you to an incredible place, and along the way, you’ll meet some fascinating people and hear their stories. Our theme and end credit music is composed by Sam Tyndall.
