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

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
