In the 1920s, J Harlen Bretz was ridiculed for suggesting a massive flood carved the Pacific Northwest. But he was right. Lake Missoula—held back by ice—burst free, unleashing a torrent that tore through the Columbia River Gorge with tornado-like turbulence, carving canyons in days. What Bretz called a “recessional cataract”… was a fossil of catastrophe. | The Randall Carlson

The Bonneville and Missoula floods—two of the most catastrophic events in North American history—are thought to be unrelated. But what if they weren’t? What if they happened together, triggered by a single, greater cause? Coincidence... or convergence? Join Randall Carlson on the Lake Bonneville Megafloods Tour and explore the evidence firsthand. Witness the landscapes shaped by these ancient deluges and uncover the secrets of Earth's past. Reserve your spot now—link in bio! | The Randall Carlso

We talk about the melting ice sheets—but where did all that water actually go? Exploring the Missoula Floods in the 1980s raised a bigger mystery: There are massive, unexplained gaps in the landscape… and nature doesn’t care about our research boundaries. The jet stream moves. The floods come. And the truth? It’s outside the box. | The Randall Carlson

The Bonneville Flood, North America’s second-largest documented flood, occurred at the end of the last ice age. Triggered by the drainage of a massive lake covering nearly 100,000 square kilometers and nearly 1,000 feet deep, it discharged at an astonishing rate of 40 million cubic feet per second. Its connection to the Missoula Flood remains a fascinating and controversial topic in geological studies. | The Randall Carlson

Once Cold War walls fell, U.S. scientists gained access to Russian geological records—and found something staggering: the Altai Flood. Catastrophic flows on the same scale as the Missoula Flood—800 million cubic feet per second—swept across Siberia. And the timing? It lines up with the Ice Age melt in North America. One planet. Multiple cataclysms. | The Randall Carlson

Imagine walls of water, thousands of feet deep, tearing through canyons and reshaping continents. The Bonneville flood drained an inland sea the size of West Virginia. The Missoula flood released torrents that dwarfed the Amazon. These weren’t separate accidents of nature — their paths crossed, their forces combined. Two catastrophes colliding, leaving scars still visible on the land today. | The Randall Carlson
