In this episode of The Atlas Obscura Podcast, we visit Fishlake National Forest, home to the biggest organism by mass on the planet. But this giant is shrinking and an unusual group has banded together to help defend it.

We have a new book coming out! It’s called Gastro Obscura: A Food Adventurer’s Guide, a whirlwind tour of the world’s edible wonders. Pre-order your copy, and as a bonus you’ll get some mathematically efficient cookie cutters!

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.
