Such was the case with the Hy?jun Maru, which was left rudderless in a typhoon off Japan and drifted for 14 months before washing up in 1834 on Washington state’s Cape Flattery headlands, just across from Pachena Bay. It contained three fishermen.
It is, in fact, one of 100 known Asian drift boats that have crossed the Pacific accidentally. (The last one to arrive came ashore on the Queen Charlotte Islands in 1987, empty.) But no one knows what to make of the evidence hauled up from the wreck that lies 16 kilometres off Pachena Bay in almost 150 metres of water, or the two supposed wrecks that are purported to have yielded strange artifacts from beneath nearby Clayoquot Sound. For all three have produced barnacle-covered Asian pots—probably Chinese—whose age may predate the earliest European visitors to this coast.
Pretty good long article.
