megaflood
Ancient massive torrent
A megaflood is a catastrophic flood of extraordinary magnitude, typically releasing water volumes far exceeding anything in recorded human history.
The term usually describes prehistoric events like the Missoula Floods, which carved the Pacific Northwest's channeled scablands, or catastrophic dam failures.
Geologists identify megafloods by the massive erosional features they leave behind: giant ripple marks, deep channels cut through bedrock, and enormous boulders transported miles from their source.
