[00:00:00]14,000 years ago a catastrophic flood in Siberia was so massive it carved features into bedrock that are still visible from satellites today. Imagine an ice-dammed glacial lake holding back 600 cubic kilometers of water. Then imagine the dam failing. The water that came loose was a wall of liquid 400 meters deep >> [music] >> traveling at 90 kilometers per hour down the Chuja and Katun River valleys. This wasn't just fast-moving water. It was a devastating force of nature.

[00:00:28]It carried boulders the size of houses and deposited them 300 [music] meters above where the valley floor sits right now. The flood scoured the landscape so intensely that it left bedrock ripple [music] marks that stand 20 meters tall.

[00:00:41]Scientists have confirmed this was the largest known terrestrial flood in Earth's entire geological record. But here's what's wild. Most people have never heard of it.

[00:00:51]This ancient catastrophe reshaped an entire [music] region proving that our planet has survived forces almost incomprehensible to the human mind.
