Bluefish and Old Crow are north of the central part of Canada
where the "ice-free corridor" between the Cordellerian
and Greenland glaciations existed.  I think it more accurate to
say that the Bluefish region and the "corridor" was potentially
habitable from at least 40-50,000 years ago until Clovis times.  If
the corrider "closed" it was not until after about 20,000 years ago
and (if closed) did not re-open until about Clovis times.  The
"corridor" is a moot question before and after 20-12 kyr BP, but if
people managed to reach Bluefish/Old Crow 40-25,000 years ago,
there is no "glaciation" reason why they would necessarily have to
retreat.  And before "closure" there's no reason why they could
not use central Canada as a route south.  Bluefish/Old Crow were
never covered by the late Wisconsin glaciation (LGM).
