Well, thats possible.  But lets think about it for a moment.  If this
migration occurred lets say 60kya, there would be several glacial
advances between then and now and a lot of "earthmoving"
could have occured.  If I go back 30kya, there is progressively
fewer "advances", and more of a pseudo "static situation" and retreat
of the glaciers, right?  How does that get you "plowed under"?

As for the possible interference by modern humans and such,. . .
would not that same agent have destroyed all evidence of Folsom
and Clovis as well?
