What causes flash floods? Here's how they get so destructive so quickly

The largest freshwater floods on record weren’t rivers...they were inland oceans. At the end of the last Ice Age, walls of water thousands of feet deep and miles wide swept across the continent. Glacial Lake Missoula alone held more than 2,500 cubic kilometers of water before erupting in cataclysmic outbursts. If a flood of that scale happened today, it would be the most extraordinary event in human history. | The Randall Carlson
