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?

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.

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?

For the project’s creators, that meant great success, but it also meant facing pushback and surprises. We talk to journalist Nikole Hannah-Jones about how politics affected The 1619 Project and what it means to be in the middle of this social reckoning. For more information on this episode, visit natgeo.com/overheard. Want more? The 1619 Project documentary examines how the legacy of slavery has influenced music, capitalism, and democracy itself.
