How 7,000 Years of Epic Floods Changed the World (w/ SciShow!)

Thumbs down for exclusive use of the metric system.

love the hardcore hometown shoutouts

Whoa! What's with all that loud banging on piano? Cut it down.

Also what broke the glacier damn

Isn’t it more likely that it happened in one epic flood and not a bunch of smaller ones to make such large land impressions?

Isn't this hypothesis being questioned, as of late? With the increasing evidence of a catastrophic impact event across the North American Ice Sheets, causing the Younger Dryas? I don't doubt there were many floods, but the recent published papers on this subject provide compelling evidence that this was the cause of a major impactor, or rather, multiple impactors, spread across North America, Greenland, and North Western Europe

How about one great flood that involved massive plate shifts, buckling & zippering? What if the flooding and massive changing currents lasted for a year? Multiple natural dam bursts one after another.

Did this inspire the Valles Marineris flood descriptions in Kim Stanley Robinson's Red Mars and sequel?

Love a good detective story. Very interesting stuff.

Check out Nick Zentner’s channels like huge floods if you are interested in the geology of North America. The guy is wise and entertaining.

Randall Carlson is continuing Brett's work... search for his video series!

Yall should just give Randall Carlson his credit on this topic

If post 10 was there he would’ve drained the floods

Excellent! Isn't Venice sinking though as opposed to sea levels rising? Before "climate change" that was the cause.

title says "Changed the World"video says "Changed Idaho"yawn

Lol I would not wanna witness those floods... probably be the last thing I'd ever witness.

I like the non animal vids you guys do. Keep them coming.

Learned about this 2-3 years ago on a Joe Rogan podcast with Randall Carlson!

But yet there's no evidence for the biblical floods...right

My 2 favorite education channels in one video

im pretty sure 7k years of flood would change how things look

Eastern British Columbia has evidence of a great cataclysm, which happens to be North of the scablands. It looks as if some large asteroid slammed into the Cordilleran ice sheet, the melt water runoff erosion patterns run in all directions, even South toward the scablands.

I first learned about this on the Joe Rogan podcast last year with Randall Carlson as a guest. I wonder if some of the people behind PBS eons also watched the same episode, it was really interesting stuff. If you want more in-depth details I would recommend the first episode of Randall Carlson on JRE.. try it out

One of the most amazing short episodes ever.

its was an asteroid, meteor, that caused it.

so where does Randall Carlson's work w/ the Younger Dryas period further north in Canada fit in w/ Bretz and Pardee's work?

Being raised in Washington this is something we cover in, still an awesome video especially for those not raised here.

This was caused by one large flood. Not a series of floods. Large scale comet/meteor made contact with the earth about 12,800 years ago. Causing the extinction of large mammals throughout the world, but largely affecting North America.

Two words - Randal Carlson

How did some flood in Missoula(?) change the world? I've loved Eons vids until now with this clickbait title. I thought I was about that huge flood that flooded Doggerland (between UK and Norway) and created a tsunami reached the entire globe, or something on that scale. Not some local flood.

It would've been the last thing you ever say. The last terrifying thing.

The ancient humans invented swear words when they saw that wall of water.

You guys should do a video on how the great lakes formed especially lake superior with how it used to be volcanic.

and the meteor strike on newfoundland 11000 years ago.. ????

Great video! Thanks

7,000 years?Any intelligent person knows it was only a little over 1 month.....

Dry Falls is amazing. All the scablands give pause.

Randall Carson said it best

This is one of my favorite Eons episodes!I have an idea for an alternate history story about people witnessing the floods caused by Lake Agassiz, so this episode made me super happy!

All the millions of animals killed by those floods :-(
