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

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
