Captain Mike Perna has spent 25 years doing something most people think only happens in movies: diving for sunken Spanish treasure. Off Florida's Treasure Coast lie the scattered remains of the 1715 Plate Fleet — eleven galleons loaded with New World gold and silver that a hurricane drove onto the reefs in a single night, killing over a thousand people and strewing their cargo across miles of ocean floor.

This past summer, Mike's crew pulled 1,051 silver coins off the seabed and made national news. He flew from Florida to Montana to tell us how it actually works: the "breadcrumb trails" of coins scattered a mile from the wreck, the magnetometers and metal detectors, the short summer dive season, and the "you never really own the treasure, you just hold onto it for a while" philosophy that comes with a quarter-century of doing it. He brought real pieces of eight to pass across the table, walked us through the legendary Mel Fisher and the $400 million Atocha, and got into the thorny ethics of who really gets to keep history.

Whether you're here for shipwrecks, colonial history, or just a great real-life treasure story, this one's got gold, pirates, hurricanes, and a lead box packed with 16,000 pearls.

David Good grew up with one foot in suburban Pennsylvania and the other in the Amazon rainforest. His father, anthropologist Ken Good, spent 12 years living with the Yanomami — one of the last relatively isolated peoples on Earth — and married David's mother, Yarima, the daughter of a headman. Then, when David was six, Yarima walked back into the jungle and didn't come out. He wouldn't see her again for 20 years.

This is the story of what happened next: two decades of trying to bury his own identity, and then a bug-fearing 24-year-old's decision to travel days up the Orinoco River to find the mother he thought had abandoned him. What he found reframed his entire life — a family, a new name, a brother he would later grieve in a Yanomami funeral, and a scientific calling studying the Yanomami gut microbiome, which may hold clues to the diseases of the modern world.

David is a microbiome researcher at the University of Guelph, the founder of the Yanomami Foundation, and the subject of the new documentary WAYUMI. This is one of the most singular life stories we've ever had on the show.

Who was responsible for the disappearance of Amelia Earhart? Was it her oft-drunk but undeniably brilliant navigator, Fred Noonan? Her publicist husband, George Putnam, who pushed his wife toward the PR stunt of the century despite her relative mediocrity as a pilot? Or was it Earhart herself, whose sudden fame had begun to cloud the thing a pilot needs most: her judgment?

Journalist Laurie Gwen Shapiro — a contributor to The New York Times and The Atlantic — spent five years going where no Earhart biographer had gone before. What she found isn't the flawless icon, but a real and complicated woman. Today, Laurie gives us a portrait of the person behind the legend and a deep dive into Earhart's final flight and July 1937 disappearance over the Pacific: a stretched budget, a dropped antenna on the Lockheed Electra, an alcoholic navigator hired because he was cheap, and a pilot who was sick, exhausted, and out of fuel as she searched for tiny Howland Island.

We get into the enduring mystery and the theories it spawned — and why the real story of what happened to Amelia Earhart may be sadder, and more human, than any of them.

Shapiro's book, The Aviator and the Showman: Amelia Earhart, George Putnam, and the Marriage That Made an American Icon, was named a New Yorker Best Book of 2025.

Cody Lundin has spent 34 years keeping people alive. Almost none of it looks like what you've seen on TV. He's the founder of Arizona's Aboriginal Living Skills School, an EMT since 1993, the author of 98.6 Degrees: The Art of Keeping Your Ass Alive and When All Hell Breaks Loose, and one of the two original hosts of Discovery's Dual Survival. He built (and nearly broke) his career by refusing to fake it for the camera.

We flew Cody up to Bozeman, took him duck hunting at the crack of dawn (his very first time), and then sat down for one of the most no-BS survival conversations we've ever recorded. Hayden throws him a series of escalating worst-case scenarios: a desert breakdown, a broken leg in the Colorado high country, a hiker lost at an alpine lake. Cody refuses every easy answer, demanding context and walking through what staying alive actually requires (hint: it's rarely the sexy stuff). Along the way: the physics of freezing to death, why your survival shelter should be invisible, the truth about what survival television did to his profession, and the on-camera stand that cost him his show. Producer Andrew even gets pulled in to defend his off-grid cabin.

Steven Callahan should have died at sea. In early 1982, roughly a week out of the Canary Islands, something — he's convinced it was a whale — holed his self-built 21-foot sloop Napoleon Solo in the middle of the night. What followed became one of the most famous survival stories ever told: 76 days adrift in a five-and-a-half-foot inflatable raft, alone, crossing nearly the entire Atlantic before a handful of fishermen found him off Marie Galante.

In this conversation, Steven walks us through all of it — diving into the flooded, pitch-black cabin to grab his ditch kit, coaxing a single pint of fresh water a day out of a temperamental solar still, spearfishing the dorado that became both his food and his "spiritual companions," and the Day-43 disaster when his spear gun punctured the raft a thousand miles from land. But this is less a blow-by-blow than a master class in the psychology of survival from a philosophy major who treats reality as something to be accepted exactly as it is. We get into the divided self, the brutal "recoil" of giving up, why denial is the number one enemy, and how an ocean nearly killed him and gave him a life.

Your social studies teacher gave you Henry Hudson in about two sentences: a guy, a river, New York. Dr. Peter Mancall — USC historian and author of Fatal Journey and the new continental history Contested Continent — is here to give you the other 99%. We start with Hudson's doomed final voyage: iced into the bottom of Hudson Bay for a brutal winter, a starving crew, a mutiny, and a captain set adrift in a rowboat never to be seen again. Then we zoom all the way out.

This is a two-hour tour through the early America that gets left on the cutting-room floor — the fur trade and the "perfect trade good" of alcohol, John Adams' filthiest joke, the cannibalized girl of Jamestown, Columbus's fall from hero to villain, Cahokia's lost pyramid city, the Vikings who quit North America, and the 1680 Pueblo Revolt that scrubbed an empire off the map. It's bloody, it's funny, and it'll permanently change how you hear the word "Thanksgiving."

If you love history that refuses to flatten people into heroes or villains, this one's for you.

Lincoln Knowles is 21 years old, lives out of his Jeep, and has the climbing internet at war with itself. To half the community he's a reckless idiot free soloing a harder route every day until he falls; to the other half he's the funniest, most self-aware thing to happen to the sport in years. The truth — as Hayden finds out — is that the kid is a genuinely elite climber (a sub-10-hour Nose-in-a-Day, on-sight free solos in Yosemite, V11 on the board) who's running the most committed satire in outdoor media.

This one goes everywhere: Lincoln's Yosemite "tear" and a storm-soaked bail off the Nose, a surprise call to climbing legend John Long, the Alex Honnold text and the Climbing magazine hit piece, and an extended phone-in from Cedar Wright, who makes the full punk-rock case for why this stuff matters. It's funny, it's genuinely unsettling when the talk turns to mortality, and it's impossible to look away from. Whether you think he's the future of the sport or a tragedy waiting to happen, you'll understand exactly why everyone's arguing about him.

Adam Weaver holds the world record for the farthest anyone has ever traveled from a cave entrance — miles of crawling and climbing into a place no helicopter or rescue team can reach. He edits NSS News, America's only national caving magazine, and was recently tapped by ABC News to break down the Laos cave rescue for the public.

In one of the most genuinely unsettling episodes we've recorded (Andrew does NOT like caves), Adam gets into the gear, the 9-inch passages, and the very real ways a cave can kill you — plus the full story of a teenager trapped a mile deep, 24,000-year-old mummified animals, and a quarter-mile traverse with no floor.

Is Everest still a climber's ultimate test, or has it become too crowded and controversial?

This week on The Backcountry Manifesto, Everest historian, climber, and 1999 Mallory expedition participant Tom Pollard joins host Hayden Sammak in PART 3 of our discussion to share his gripping firsthand stories. We dive into Tom's four Everest attempts, his 2016 summit triumph, the evolution of guiding from pre-1996 pioneers to today's high-stakes operators, and the raw power of Sherpa climbers. Plus, breakdowns of key landmarks like the Hillary Step and South Col, the perils of avalanches and bottlenecks, debunking myths around "Into Thin Air," and reflections on what Everest truly represents beyond the hype. If you're fascinated by high-altitude adventure, mountaineering history, or the human spirit against nature's extremes, this episode is your summit push.

We talk about:

On this episode of the Backcountry Manifesto, we're taking you on a Montana backcountry adventure guided by the one and only Dr. Hoby Wedler. Dr. Hoby is a wildly popular sensory storyteller who explores the world around him using sound, smell, taste and touch to offer his fans and followers a unique perspective on the world around him. 

From foraging early-season chanterelles in undisclosed forests (complete with their apricot-plum aroma), to metal detecting for gold nuggets in historic mining districts, and mastering fly fishing on the Yellowstone River amid thunderstorms and swallow-filled caves, Hoby describes his backcountry adventure. We also dive into whiskey tastings, elk dinners with wild mushrooms, and life lessons on embracing challenges, preparation for adventure, and positivity. Later, Hoby ranks his favorite experiences during his Montana mission and offers his thoughts on fearlessness in the face of new experiences.

You've likely listened to countless podcasts on backcountry adventure, but none quite like this.
