If true, he asked, why wouldn't archeologists find evidence of older and more developed civilizations in Alaska, British Columbia and the Northwest and newer, more rudimentary civilizations as the migration route turned south? Instead, we find exactly the opposite.

One explanation that occurs to me is that the crossers did not stop in Alaska, because of the inhospitable climate. People who lived there were naturally living at a subsistence level.

Alaska, yes. But you have some pretty mild climates in the Pacific Northwest and all the way down the California coast. The Chumash tribe, centered around present day Santa Barbara, never put up anything even close to the Inca, Maya, Aztec, Toltec and a score of others further south.
