Drowned Highways: The Violent Erasure of the Bering Land Bridge

Beschreibung

They walked across a continent that no longer exists. When the ice melted, the ocean rushed in and permanently locked the door behind them.
The first humans to populate the Americas did not arrive by boat; they walked across a massive, flourishing continent that connected modern-day Siberia to Alaska. This was Beringia, a sprawling, ice-free steppe that served as the ultimate prehistoric superhighway. And then, it vanished entirely beneath the ocean. As the last Ice Age ended, global temperatures surged, causing the massive continental ice sheets to collapse. This book explores the violent, rapid geological submergence of Beringia. It was not a slow, gentle trickle, but a catastrophic series of meltwater pulses that violently tore the land bridge apart, permanently isolating the flora, fauna, and human populations of the Americas from the rest of the globe. We dive into the paleoclimatology used to map this sunken continent and analyze the desperate survival strategies of the nomadic tribes caught in a rapidly shrinking, flooding world. Witness the birth of the Pacific divide. A geological thriller about the day the ocean swallowed the only road connecting two hemispheres.
