It would be tempting to project the tomol backward 13,000 years, to imagine the Arlington Springs individual crossing the channel in something like it.

This projection is not supported by any evidence.

The historical tomol is documented from the eighteenth century onward; the archaeological evidence for plank canoes extends back into the prehistoric period in the Channel Islands region, but not to 13,000 years before present.

The vessels used by the terminal Pleistocene inhabitants of the coast — if they were watercraft as opposed to simple rafts — are entirely unknown in their specific design.

What can be said is that some form of water transport was required.
