Short version: Spanish galleon shipwrecks off the Pacific Northwest coast, long before we thought there were trade routes.

The evidence is good, but still circumstantial. Kinda.

PNW native tribes using Chinese pottery for arrowheads?!?

Beeswax washing up on shore for centuries?

PNW Natives claiming African descent?

A large pool of mercury sitting at the bottom of the ocean?

This is just fascinating stuff.
