The Bluefish Caves evidence is relevant to both route hypotheses, though in different ways.

If people were in eastern Beringia 24,000 years ago, then they were in the right place at the right time to have been the populations that eventually moved south through either the ice-free corridor or the coastal route — or both — as those routes opened at the end of the Last Glacial Maximum.

The archaeological evidence from Bluefish Caves does not itself tell us which route was used, but it supports the presence of a population in Beringia that would have had the opportunity to use whatever routes became available.
