[Alas Babylon!]

Scientific America did a great review on these issues in their September, 2000 issue. They included a great map here showing the various sites (some are now identified as 30,000 years old) and possible migration routes.

(I've read subsequent reports that state that the tools found there are similar to the technology present at the time on the Iberian peninsula. Early Basque?)

Note the Atlantic crossing route. It has now been theorized that Cro-Magnon Man's (from Iberia and Southern France) Solutrean stone points and Clovis points are VERY similar.
