20000 to 18000 BCE. Living in Florida would be like WTF? First the ocean inundates 100 miles inland over 750 years, then the oceans go back out over another 750 years. Two opposite clan-community history themes. First retreating from water, then chasing it out... then the ocean comes in again, and keep coming in. Woe to those with historic expectations. The water kept coming in. Like a bear stock market.

What I find interesting is that the interior of Alaska was not under ice - the topography was so clearly erosion-dominated and more reminiscent of what one finds in Japan and so completely different from, say, Scandinavia...

This is not accurate. Glaciers didnt recede that early and no younger dryas event

There is no arctic sea ice by 9000 ybp, which is wrong. There still is today. Is this just made up bs?

If this map is accurate concerning the Aleutian islands and sea ice, why would it not have been possible for the earliest humans to cross from Siberia to the Alaskan coastline by island hopping using frozen sea ice or boats or a combination of the two, as early as 20-30k years ago, rather than crossing using the Berengia ice-free corridor theory many thousands of years later? There are a growing number of discoveries showing early human settlement in South America and in North America (such as the footprints discovered at White Sands New Mexico) that predate the ice-free corridor by several thousand years. That theory may account for some migration, but it doesn't seem to hold up as far as being the only time or even the first time that humans crossed into North America.

Can you show how it affected Europe the Mediterranean? They say the floods from this melt caused the Flood Myths

Loved this video! I am a lover of history, geography, astronomy, astrology, etc.

I wonder if Vancouver Island and the Queen Charlette Islands connected to the mainland during the Last Glacial Maximum.

For the western sector, ice positions were “extrapolated” to eastern positions without dating, and without other ice position information (such as moraines). It’s all speculation, and reinforced by minimum dates that don’t record actual ice positions.

Yo man, i am excited for this, can't wait!

Beautifully done! Can´t wait for the sequence.

just found out about your channel! One of my favorites! Great amount of detail :D

Nice that’s cool!

Not sure where the sequence is from or how data was applied, but it is my understanding that the driftless region of south western Wisconsin, north eastern Iowa and south eastern Minnesota were never fully covered by this glacial advance. I could be wrong. College was in the nineties. Maybe I've just been telling myself the wrong thing when I get down in those valleys trying to catch native trout.

Epic! Well done. Great animation.

neat

Where's lakes Agassi and Ojibway?

and welcome to ancient architects

me likey

Two years have passed and there's still no North American video.
