Surviving -40°F: The "Invisible Wall" Inside the Native American Tipi || Sleep Silent History

Surviving -40°F: The "Invisible Wall" Inside the Native American Tipi || Sleep Silent History ​In the dead of winter, temperatures on the Great Plains could drop to -40°F—cold enough to make trees explode. Yet, inside a thin layer of buffalo skin, Native American families were warm and comfortable. How? ​European settlers often looked at the Tipi and saw a flimsy tent. They were wrong. They were looking at one of the most sophisticated pieces of aerodynamic engineering in human history. ​In this Story, we reveal the "Lost Technology" of the Native American winter survival strategy. From the physics of the "Invisible Wall" (Dew Cloth) that created a central heating system, to the biological insulation of buffalo robes, and the high-fat diet that turned the human body into a furnace. ​Discover how the Lakota and Plains tribes didn't just survive the "Moon of Popping Trees"—they mastered it.
