Map of Pleistocene lakes in the Western US, showing the path of the Bonneville Flood along the Snake River
The Bonneville flood was a catastrophic flooding event in the last ice age, which involved massive amounts of water inundating parts of southern Idaho and eastern Washington along the course of the Snake River. Unlike the Missoula Floods, which also occurred during the same period in the Pacific Northwest, the Bonneville flood happened only once. It is believed to be the second-largest flood in known geologic history.[1][clarification needed]
