    Trapped in the icy waters of the Northwest Passage

    For centuries, the Northwest Passage, the long-sought sea route connecting the Atlantic and Pacific Oceans through northern Canada, was a holy grail of Arctic exploration. Even now, sailing through it isn’t guaranteed. Mark Synnott, a National Geographic Explorer, writer, and adventurer, attempted to sail his own boat through the Northwest Passage to retrace the doomed 1845 expedition of British explorer Sir John Franklin. None of the Franklin expedition’s 129 men made it home, but what exactly happened remains a mystery.   For more information on this episode, visit natgeo.com/overheard. Want more? Get the inside scoop on Mark’s Northwest Passage voyage and see gorgeous photos in the August issue of National Geographic. Watch Explorer: Lost in the Arctic, premiering August 24 on National Geographic and streaming the next day on Disney+ and Hulu. And to go even deeper, Mark will tell the full story in his book Into the Ice, coming fall 2024 from Dutton, an imprint of Penguin Publishing Group. Also explore: On paper, Sir John Franklin’s expedition seemed to lack for little. There were ironclad ships, steam engines, libraries totaling 2,900 books, and even animal companions—two dogs and a monkey. Here’s how it all went wrong.

    Playback: Modern Lives, Ancient Caves

    There’s a lost continent waiting to be explored, and it’s right below our feet. We’ll dig into the deep human relationship to the underground—and why we understand it from an instinctive point of view, but not so much from a physical one. (Hint: We’re afraid of the dark.) In an episode originally published November 2021, National Geographic photographer Tamara Merino will take us subterranean in Utah, Australia, and Spain, where modern-day cave dwellers teach us how to escape the heat. For more information on this episode, visit natgeo.com/overheard. Want more? Go below ground with National Geographic Explorer Tamara Merino to see how these communities have been living—quite comfortably—for a very long time. In Vietnam photojournalist and National Geographic Explorer Martin Edström created 360 images of the world’s largest cave, Son Doong. It’s so big that a forest grows inside of it. Ever zip-line to a remote island? Cartographers did, 30 miles west of San Francisco. What did they see when they mapped the hard-to-reach landform known as the Farallon Islands? Caves. China is home to some of the most intricate cave systems on the planet. These explorers used a laser scanner to capture never before seen images of undocumented caves.

    Playback: This Indigenous Practice Fights Fire with Fire

    For decades, the U.S. government evangelized fire suppression, most famously through Smokey Bear’s wildfire prevention campaign. But as climate change continues to exacerbate wildfire seasons and a growing body of scientific research supports using fire to fight fire, Indigenous groups in the Klamath Basin are reviving cultural burning practices that effectively controlled forest fires for centuries. In an episode originally published June 2022, National Geographic photographer Kiliii Yüyan introduces us to people bringing back this cultural practice and teaching the next generation how to use fire. For more information on this episode, visit natgeo.com/overheard. Want more? If you want to hear more from Kiliii, you can also listen to a previous Overheard episode where he shares stories from the many weeks he spent camping on sea ice with Native Alaskan whale hunters. And if you’re dying to see his photography, check out his website to see portraits of Indigenous people, Arctic wildlife, and more. Also explore: To learn more about Margo Robbins and her efforts to revive cultural burns, check out our article on the subject. The practice of cultural burning is just one of many subjects that Kiliii and writer Charles Mann covered about the ways Indigenous groups are trying to reclaim sovereignty.

    Playback: Rooting, from Into the Depths

    National Geographic Explorer Tara Roberts is inspired by the stories of the Clotilda, a ship that illegally arrived in Mobile, Alabama, in 1860, and of Africatown, created by those on the vessel—a community that still exists today. The archaeologists and divers leading the search for the Clotilda lay out the steps it took to find it. In this last episode of the Into the Depths podcast, which published in March 2022, Tara talks to the living descendants of those aboard the ship. She admires their enormous pride in knowing their ancestry, and wonders if she can trace her own ancestors back to a ship. She hires a genealogist and visits her family’s small hometown in North Carolina. The surprising results bring a sense of belonging to a place that she never could have imagined. Want more? Check out our Into the Depths hub to listen to all six episodes, learn more about Tara’s journey following Black scuba divers, find previous Nat Geo coverage on the search for slave shipwrecks, and read the March 2022 cover story. And download a tool kit for hosting an Into the Depths listening party to spark conversation and journey deeper into the material. Also explore:  Dive into more of National Geographic’s coverage of the Clotilda with articles looking at scientists’ ongoing archaeological work, the story that broke the discovery of the ship, and the documentary Clotilda: Last American Slave Ship. Meet more of the descendants of the Africans trafficked to the U.S. aboard the Clotilda, and find out what they’re doing to save Mobile’s Africatown community in the face of difficult economic and environmental challenges.  Read the story of Kossola, who later received the name Cudjo Lewis, in the book Barracoon: The Story of the Last “Black Cargo,” by author and anthropologist Zora Neale Hurston.

    Playback: Ancient Orchestra

    Sound on! From conch shells to bone flutes, humans have been making musical instruments for tens of thousands of years. What did prehistoric music sound like? In an episode originally published in November 2021, follow us on a journey to find the oldest musical instruments and combine them into one big orchestra of human history. For more information on this episode, visit natgeo.com/overheard. Want More? A conch is more than just a musical instrument. A mollusk lives in that shell, and it’s a staple food in the Bahamas—so much so that overfishing is threatening their existence, but a few simple solutions may solve the problem. The oldest musical instrument was once thought to be a cave bear bone flute made by Neanderthals, but recent evidence suggests that the holes were made by animals rather than tools. More information about each instrument: The organization First Sounds found and brought to life the recordings of Édouard-Léon Scott de Martinville. Head to their website to learn more about that project. Bettina Joy de Guzman travels the world, composing and performing music on ancient instruments. You can read more about her work on her website. More information about the bells of Bronze Age China can be found at the Smithsonian's National Museum of Asian Art. Check out a virtual version of their collection.  The conch shell sounds you heard were research recordings of the approximately 3,000-year-old Titanostrombus galeatus conch shell horn—excavated in 2018 by John Rick and a team from the UNESCO World Heritage archaeological site Chavín de Huántar, in Perú. You can read more about that research at the Chavín de Huántar Archaeological Acoustics project website. National Geographic Explorer Jahawi Bertolli is collecting the sounds of rock gongs from all over the African continent. Learn more about his rock project on Jahawi’s website. Flutist Anna Potengowski specializes in recreating the sounds of ancient flutes. You can hear more of her work on her Spotify page. Learn more about your ad choices.

    Playback: A Skeptic's Guide to Loving Bats

    Blood-sucking villains. Spooky specters of the night. Our views of bats are often based more on fiction than fact. Enter National Geographic Explorer at Large Rodrigo Medellín, aka the Bat Man of Mexico. For decades, he’s waged a charm offensive to show the world how much we need bats, from the clothes we wear to a sip of tequila at the end of a long day. The COVID-19 pandemic caused even more harmful bat myths and gave Medellín the biggest challenge of his career. In this episode originally published in 2021, learn why the world must once again realize that bats may not be the hero everyone wants—but they’re the hero we need. For more information on this episode, visit natgeo.com/overheard. Want more? See how Rodrigo uses a multi-pronged approach—involving field research, conservation, and tequila—to help protect bats.  In a Nat Geo short film, Rodrigo ventures into an ancient Mayan ruin to find two rare species of vampire bat. Curious about the connection between bats and Covid-19? Explore why it’s so tricky to trace the disease’s origins.   Also explore: Learn more about bats: They can be found nearly everywhere on Earth and range in size from lighter than a penny to a six-foot wingspan.    Why do bats get a bad rap? See how Spanish conquistadors and Dracula convinced us bats are more fright than friend.  Bat myths have real-world consequences. In Mauritius, a government campaign culled tens of thousands of endangered fruit bats.  For more bat info, follow Rodrigo on Instagram @batmanmedellin. Learn more about your ad choices.

    How queer identity shapes Nat Geo Explorers

    Why would a scientist brave the stench of a car full of rotting meat on a 120-degree day? What can a unique whistling language teach us about humans’ connection to the natural world? And how does queer identity shape the research of National Geographic Explorers? In this episode celebrating Pride, we hand the mic to two Explorers: Christine Wilkinson, who studies hyenas and other large carnivores and created the TikTok series “Queer is Natural,” and Rüdiger Ortiz-Álvarez, whose soundscapes from the Canary Islands encourage us to slow down and listen to the world around us. For more information on this episode, visit natgeo.com/overheard. Want more? Why do some people prefer LGBTQIA+ instead of LGBT? See how society’s understanding of diverse sexual identities and gender expressions has grown more inclusive—and so has the acronym used to describe them. Before the Nazis rose to power, a German institute cemented itself as gay liberation’s epicenter. Discover the great hunt for the world's first LGBTQ archive. Although a large group of LGBTQ people celebrating their sexual orientation in public had been unthinkable just a few years before, the first Pride parades began in 1970 as marches commemorating the 1969 Stonewall uprising. See more National Geographic coverage of Pride at natgeo.com/Pride.  Also explore: Learn more about spotted hyenas, which live in female-led clans of up to 80 individuals. Practice your whistling and head to La Gomera in the Canary Islands, home to the Silbo Gomero whistling language and Garajonay National Park. Find Christine Wilkinson’s “Queer is Natural” series on her TikTok, @scrappynaturalist. And follow along with Rüdiger Ortiz-Álvarez on his Instagram, @rudigerortiz. Learn more about your ad choices.

    A Mexican Wolf Pup’s Journey into the Wild

    For centuries, Mexican gray wolves roamed the Southwest. But as cattle ranches spread, wolves became enemy number one, and by the 1970s the subspecies was nearly extinct. But after the Endangered Species Act was passed, the U.S. embarked on an ambitious plan to save the iconic predators. We’ll meet the Texas trapper who switched from killing wolves to catching them to breed. And we’ll follow a team of biologists into the Gila Wilderness to introduce captive-born wolf pups into the wild. For more information on this episode, visit natgeo.com/overheard. Want more? Check out Peter Gwin's feature article on the Gila wilderness. Thinking of visiting the Gila yourself? We've put together a travel guide for you. Also Explore In 2021, a Mexican wolf named Mr. Goodbar crossed the border from Mexico into the United States, raising questions about how the border wall will affect animal migration. The Gila wilderness is also famous for one of the only venomous lizards in the world, the Gila monster. But climate change and human activity is threatening this charismatic reptile.
