>>920317theres quite a few theories about how humans dispersed in the new world. The most accepted theory out there is that humans followed the coastline and dispersed inland from the western coasts. Like I said, "impassable" does not mean "there is no possible way to go there" it means its very very difficult and impractical for nearly every situation in our day and age. Humans could have crossed the cascades, they came from Siberia, crossed the bearing land bridge during peak glaciation of our last ice age, they were very adept at extreme arctic conditions. We are not paleolithic arctic hunter gatherers, we are post industrial humans, we don't have generations of survivalism in the planet's harshest conditions, we grow up in cities. Humans have also summited Everest, but the Himalayas are by all practical means, impassible. Not impossible to cross, but impassible. Again, you are not a rugged survivalist mountain man, don't try to walk over fucking mountains because you have a fancy bushknife and jacket
