159K views · 2.3K reactions | 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 | Facebook

647K views · 5.8K reactions | 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 | Facebook

79K views · 1.3K reactions | When the Missoula floods surged into the Snake River, they backflooded 150 miles upstream, leaving fine silts at the distal reach. At the same time, the Bonneville flood thundered north through Hell’s Canyon, dropping massive boulders at its mouth. At Tammany Bar, the two torrents met —coarse Bonneville gravels overlying Missoula silts —a geological record of cataclysms colliding. | The Randall Carlson | Facebook

The founders of modern geology...Cuvier, Sedgwick, Murchison...were catastrophists. They studied the Earth as it is and saw a record of upheaval: floods, quakes, and cataclysms that shaped continents. Later, the doctrine of uniformitarianism took hold ...“the present is the key to the past.” But when J. Harlan Bretz proposed massive Ice Age floods in the Pacific Northwest, his peers dismissed him. Decades later, the evidence proved him right. The Earth’s history is not slow and steady; it’s writ

One of the largest floods ever documented raced through north Idaho. It’s called the Missoula flood, and it occurred fairly recently, like 15,000 years ago. It’s one of the events we examine in “Idaho Geology, A Convergence of Wonders,” airing Sunday at 7 p.m. on Idaho Public Television. Here’s a taste of it. And you can read about it here on our website for the show. http://idahoptv.org/outdoors/shows/geology/ | Outdoor Idaho

Hurricane Katrina was devastating—but the Lake Missoula floods were on another scale entirely. Modern floods? Measured in millions of cubic feet per second. Missoula? Try 350 million. That’s up to 10 surdrops—the same unit used to measure ocean currents. And it wasn’t minutes or hours… it surged for days. We’re just beginning to grasp the true power of these ancient megafloods. | The Randall Carlson
