Most of the time when we discuss the Ice Age Floods, we are talking about the Missoula Floods which happened from 18,000-15,000 calendar years ago. Our research shows that there are many sites of much older flood deposits (they have calcite horizons in them) that show that megafloods happened throughout the Quaternary. In my book, I call them Ancient Cataclysmic Floods because we do not know where the water came from.
