I don't know a lot about the Bering land bridge, except that I live on the Alaskan side of that structure. If conditions are the same now as they were then, no one but a few hunters and berry-pickers would venture much farther than this on land. By sea, they would go to all coastal areas all up and down North and South America and spread inland from there. But going on foot in interior Alaska and presumably on the Bering land bridge would be very tedious and slow in summer, and few would go anywhere at all in winter. Population would not spread outward from Alaska at all by land routes, not in 10,000 years.
