John Orth is a violin maker from Colorado. Andrew Shapiro is a college kid from Virginia. They have little in common except that for the last two years they’ve been trading back and forth the world record for the most pull-ups in 24 hours. Over the summer, they both set their sights on 10,000 pull-ups. It’s a number that would have been unthinkable two years ago; a number that seemed like it would reveal the very limits of what the human body can do. Instead, they found a different limit.

In this first episode of a new series exploring how gear gets made, we investigate the origin of arguably the most refined fork in history. When designer Owen Mesdag was a graduate student in the late-1990s, he fell in love with a particularly clever spoon. Engineered by outdoor brand MSR, it doubled as a stove repair tool. Mesdag was enamored with it and he thought, I want to make a matching fork. And how hard could that be, really? A fork is a fairly simple tool. Except Owen’s fork didn’t just have to be good, it had to be perfect. His obsessive attention to detail meant that he kept going back to do more testing, taking more trips to Asia, and redesigning the fork again and again, because it was never quite right. Producer Alex Ward has this story explaining why the business end of a fork tells us a great deal about the tireless designers who make our favorite things.

The new movie Free Solo is arguably the greatest film about climbing that’s ever been made. In just over 90 minutes, it chronicles Alex Honnold’s astonishing no-ropes ascent of the 3,000-foot sheer face of Yosemite’s El Capitan, which he completed one morning in June, 2017. Even more impressively, it captures the unique mindset of Honnold, a perfectionist whose years-long obsessive pursuit of his dream gets complicated by an ever-present camera crew and his growing love for his new girlfriend. As you might guess, being the focus of a deeply personal Oscar-caliber documentary and then answering probing questions by a constant stream of reporters and fans has had an impact on the guy. Outside executive editor Michael Roberts chased Honnold down on his film tour to ask about the risks and rewards of telling your whole story.

Journalist Laura Krantz doesn’t believe in Bigfoot. She’s trained to be skeptical, and all the best Sasquatch sightings and photos have been debunked. Except, then she heard about Grover Krantz, a serious academic and long lost relative who had spent his career researching the possibility that an upright, bi-pedal homonid had once roamed the forest. Some of the evidence was pretty compelling, and so Laura dove into the subject headfirst. The result is Wild Thing, a nine-part series that takes a good hard look at what exactly we know and what we don’t know about Bigfoot, and why some form of this legend persists all over the world.

Maybe you saw the fire coming, maybe you didn’t. Maybe you were ready for it, maybe you weren’t. Maybe you did everything right. Maybe not. Maybe you just lost everything. Maybe that’s not even the worst of it. For this final episode of our  wildfire series, we asked fiction writer Joseph Jordan to imagine the experience of someone whose home has been destroyed by flames. He came up with a haunting story that captures our modern relationship with wildfire, in which a single catastrophic blaze is neither the start or end of anyone’s troubles.

To reduce the intensity of megafires in America, we’d need to treat and burn about 50-80 million acres of forest. So, how do we do it? What would it cost? How long would it take? Is it possible? In this episode we look at whether or not there’s anything we can do about wildfires in the West and the likelihood that we’ll take action on potential solutions.

How do you protect yourself from wildfire on a warming planet? You burn everything on purpose. No, seriously. Thanks to climate change, the whole world is a tinderbox. Fire season now starts sooner and ends later, and scientists say lightning will become more frequent, and winds more powerful. Our only defense may be intentional fires. In this episode, our friends at Outside/In take a close look at the ecology of prescription burns. Why are our forests so dependent on wildfires? And why did some plants evolve to become more flammable?

There are between eight and ten thousand wildfires in the United States each year, but most quietly burn out, and we never hear about them. The Pagami Creek Wildfire in Minnesota’s Boundary Waters Canoe Area was supposed to be like that. It was tiny and stuck in a bog that was surrounded by lakes. It was the kind of fire you could ignore. Computer models predicted that it would just sit there. But those models didn’t account for a rare convergence of atmospheric events had prepped the forest for an unprecedented burn. And Greg and Julie Welch were camping right in its path. In the first of four episodes investigating American wildfires, we tell the Welch’s extraordinary story and look at the factors that lead to this unexpected blaze.

Carina Hoang grew up in a wealthy family in Vietnam. She had a nanny to take care of her and a maid who cleaned up after her—she didn’t even wash her own hair. But when the Vietnam War broke out, she and two siblings fled the country on a boat, landing on Kuku beach, in Indonesia. It was supposed to be a refugee camp, but it was actually a deserted island. No food, no water, no buildings, people, or tools. Just sand and jungle. Produced in collaboration with Snap Judgment, with funding from the International Women’s Media Foundation, this is a story about Carina’s decades-long struggle to leave Kuku Island behind.

Most of the time, when lightning makes the news, it’s because of something outlandish—like the park ranger who was struck seven times, or the survivor who also won the lottery (the chances of which are about one in 2.6 trillion), or the guy who claimed lightning strike gave him sudden musical talent. This is not one of those stories. This is about Phil Broscovak—who was struck by lightning while on a climbing trip with family in 2005—and the confounding, bizarre science that can’t fully explain what Phil and other survivors endure in the aftermath of a strike. Originally broadcast in 2016, this episode is one of our favorites.
