That’s a lot of land! Remember, even in the warm tropics, shrunken in latitude for much, the sea was far below where it is now. Who knows what secrets from then lies on the bottom of the ocean?
Thank You for posting SunkenCiv.

I’ve never been a fan of the land bridge theory for human colonization of the Americas. But there seems to be a whole lot of people who are deeply invested in it.
Oceanic or coastal migration makes far more sense, especially for fishermen following their catch, vs trying to chase (possible) herd migrations in some of the most difficult terrain around.
So whose fault is it that we lost all that land to rising water?

All those costal rivers in the south must have supported huge runs of pacific salmon: sockeye, pink, chinook, coho, and chum. Were there were that many fish in a ready food supply there were also villages or even city sized towns dedicated to the harvest. They likely traded as far south as what is today the sea of japan. All or most of them drowned when the ice suddenly melted.
It is worth downloading the .pdf of the map, and any one who can open a .lyr doc for the hydrology.
In the fwiw department, Florida was over a hundred miles wider back then.
