Ancient footprints in New Mexico reveal new evidence of Ice Age humans that walked

Very interesting.

If people were already in North America before the Last Glacial Maximum 20,000 years ago, then they might not have had a glacial barrier right up to the Pacific Coast of North America. During the glacial build up, before the glaciers reached their maximum extent, sea levels would have been continually dropping, exposing more land that became Beringia and more Pacific Islands. So instead of following the "kelp highway" at the edge of coastal glaciers, they would have been island hopping down the Pacific Coast of what are now British Columbia, Washington, Oregon, and California.

So good places to look for early people in the Americas would be submerged islands off of the Pacific Coast. Also, along the waterways that empty into the Pacific since people would have followed them inland, south of the glaciers. Some of the ancient waterways might have been cause by glacial melt at the southern edge of the glaciers, and therefore, would no longer exist. So another area to look would be across the US in the regions that would have been a few miles south of the glaciers. They would have, at that time, been good places to live and make camps. The meltwater runoff would have created streams and lakes for plant growth, drawing animals and humans.
