The Missoula Floods are legendary—but was Lake Missoula really their source? We’re talking mega floods: water flows exceeding 1 million cubic feet per second. The Bonneville Flood hit that minimum at 35 million. Missoula? Try 10 times that—up to 400 million cubic feet per second. The landscape remembers. But are we asking the right questions? | The Randall Carlson

During the late Ice Age, massive floods tore across North America—reshaping rivers, enlarging valleys, and pouring billions of tons of water and sediment into the oceans. These weren’t just local disasters—they rewired entire drainage systems like the Mississippi, Yukon, and Columbia. The evidence is everywhere—if you know how to read the land. | The Randall Carlson

Two colossal floods—the Bonneville and Missoula—collided in prehistoric Idaho, reshaping the Pacific Northwest. Lake Bonneville, once 1,000 feet deep, burst through a natural dam and carved out the Snake River and Hells Canyon, the continent’s deepest gorge. Meanwhile, the Missoula flood surged from the north, creating a geological showdown of epic proportions. Full Episode: https://youtu.be/EsYcnXXWu08?si=PRA8hGiwzdXZYbQH | Matt Beall Podcast

The Missoula and Bonneville floods are the most famous in North American history—but they may have only been regional expressions of something much bigger. New evidence shows floods with even greater peak discharges once ripped across the continent. This wasn’t just water—it was a continental-scale catastrophe. | The Randall Carlson
