The Lake That Killed 1,700 People in One Night

If you live below a crater lake and wake up at night with a headache that won't stop — don't lie back down. And never go downhill. In 1986, Lake Nyos in Cameroon released a cloud of carbon dioxide that rolled down the valleys and killed 1,746 people in one night, some of them 15 miles away. The gas has no color and no smell. This is the story of a man who woke up below a lake like that — and what he saw when he finally opened the door. ⏱ CHAPTERS 0:00 If a lake breathes out at night 0:38 Chapter 1 — The Quiet Lake 1:49 Chapter 2 — The Headache 2:54 Chapter 3 — The River 4:13 Chapter 4 — The Diver 5:30 Chapter 5 — Up 7:05 Epilogue 7:59 The 7 rules 🧭 THE 7 RULES 1.
