When did the Missoula Floods occur?

Between 15,000 and 13,000 years ago

Where did Missoula Floods start?

At the end of the last Ice Age, 18,000 to 15,000 years ago, an ice dam in northern Idaho created Glacial Lake Missoula stretching 3,000 square miles around Missoula, Montana. The dam burst and released flood waters across Washington, down the Columbia River into Oregon before reaching the Pacific Ocean.

How many times did the Missoula flood happen?

It was the largest ice-dammed lake known to have occurred. The periodic rupturing of the ice dam resulted in the Missoula Floods – cataclysmic floods that swept across eastern Washington and down the Columbia River Gorge approximately 40 times during a 2,000 year period.

How big was Missoula Floods?

David Alt described this as “like an elephant jumping into a mud puddle” in his book, Glacial Lake Missoula and its Humongous Flood. It is estimated that the maximum rate of flow was equal to 386 million cubic feet per second. At that rate, the lake probably drained in a few days.

Could the Missoula Floods happen again?

Could huge floods on this scale happen again? Although global warming may now be a serious concern, it is likely that long-term climate cycles will cause large ice sheets to return at some time in the distant future, and cataclysmic outburst floods will probably recur in this region.

Who discovered Missoula Floods?

J Harlen Bretz

How did the Missoula Floods affect the Willamette Valley?

Today we can see how the floods impacted the landscape. They carved out more than 50 cubic miles of earth, piled mountains of gravel 30 stories high, created giant ripple marks the height of three-story buildings, and scattered 200-ton boulders from the Rockies to the Willamette Valley.

How did the Bretz floods change the Columbia Plateau?

The violent floods of water, ice and rock that swept across the Columbia Plateau moving at up to 50 miles per hour made the Snake River run backwards when the wall of water reached the Columbia River. The Columbia Gorge, between Oregon and Washington, was scoured deeply by the cataclysmic floodwaters.

What year did the Columbia River flood?

June 7, 1894 – The Great Flood of 1894

In May and June of 1894, heavy rainfall combined with spring snowmelt leading to significant flooding on the Columbia and Willamette Rivers in the Portland area. The Columbia River reached an elevation of 39.7 feet, which is still the highest flood on record to this day.

What is the largest flood in geologic history?

The largest known meteorological flood—one caused by rainfall, as in the current Mississippi River flood—happened in 1953, when the Amazon River overflowed.

Did people witness the Missoula Floods?

People, in the area since 16.6–15.3 ka, almost certainly witnessed the last of the Missoula floods and later large floods from other ice-dammed lakes in the Columbia River basin. Quantitative flow analyses give peak discharge estimates and support understanding of erosional and depositional processes.

When was the first flood recorded?

Perhaps the oldest flood story is one of the earliest stories known to man, The Epic of Gilgamesh. Recorded on 12 stone tablets this is among the first pieces of literature in history. According to the poem, Gilgamesh was a Sumerian king who reigned for 126 years.
