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. Also explore: South Dakota is famous among cavers for its web of cave mazes. Take a look at what they’ve found under the Black Hills. Learn more about your ad choices. Visit megaphone.fm/adchoices

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.
