The cliff face runs three and a half miles wide and drops four hundred feet — a cataract that, when it ran, was five times the width of Niagara and more than twice its height. Now it runs nothing but wind.","The water that made it wasn't a river. It was a flood — one of the largest the planet has ever produced, and it happened dozens of times."]},{"heading":"The flood that broke geology's rules","paragraphs":["Fifteen to twenty thousand years ago, an ice dam holding back glacial Lake Missoula — a lake the size of a small state — failed catastrophically. Walls of water hundreds of feet high tore across eastern Washington at highway speeds, scouring the land into the Channeled Scablands and pouring over the Dry Falls cataract with a volume no living river has ever matched. Then the ice dam rebuilt, the lake refilled, and it happened again — perhaps a hundred times.","When geologist J. Harlan Bretz proposed this in 1923, the establishment spent fifty years rejecting it — a catastrophe that size broke every rule of patient, gradual geology. He was right anyway. Fieldwork and direct dating vindicated him completely, and Dry Falls is now among the first 100 sites on the International Union of Geological Sciences' list of world geological heritage."]},{"heading":"Why this file matters","paragraphs":["Dry Falls is the archive's deep-time file — a place where the documented story is more violent than any legend could invent, and where being right took one stubborn scientist fifty years.
