The inland route never made any sense to me.
There’s this huge continent-wide ice sheet, maybe a mile or so thick across the upper half of North America, but there’s this nice, nifty, totally convenient for the narrative, ice-free passage for people and critters to get from Asia to North America?
And this nifty, totally convenient to the narrative gap in the massive ice walls, is itself bordered by massive ice walls, but vegetation grows thick and healthy enough to support the passage of migrating herds over thousands of miles, and it’s those herds that the “first” humans come to North America?
Uh huh.
Cool story, bro.
Thanks Grimmy, wholeheartedly agree.
