That one fact — one person, one island, one crossing, one date — is enough to establish that maritime capability existed on the terminal Pleistocene California coast.

It is enough to demonstrate that the Americas were being settled at the margins and on the islands, not only in the interior.

It is consistent with, and supportive of, the coastal migration models that have largely replaced the interior-corridor-focused Clovis First model.

But it is not proof of any complete migration theory.

A single site cannot prove a continental-scale model.

Theories of how the Americas were populated rest on accumulating evidence from many sites — Monte Verde, Paisley Caves in Oregon, the broader Channel Islands archaeological record, the Daisy Cave assemblage on San Miguel Island, sites in coastal Alaska and British Columbia, the genetic evidence from ancient and modern Indigenous populations.
