A 70-foot dock which mysteriously washed up on the west coast of America has been confirmed as coming from a Japanese harbour ripped apart by last year's tsunami.
The vast dock, which ran aground near the town of Newport, Oregon, stunned locals as it sat forebodingly on the beach.
Ap laque on the structure confirmed that the dock came from the port of Misawa in northern Japan. Three others, which have yet to be found, were also victims of the tsunami, which plunged the country into chaos.
The dock came ashore on Agate Beach, Oregon, after drifting thousands of miles
It seems that the dock travelled approximately 5,000 miles across the Pacific Coast before wedging itself on Agate Beach, Oregon.
While it is confirmed to be in no way radioactive, state police have decided to leave the dock where it is, under guard, until they are sure what to do with it.
Two possible options involve either shipping the dock to another location for safe disposal, or cutting up the dock into smaller chunks to stop it damaging other ships.

Incoming detritus from last year's tsunami in the country is causing concern, as larger objects such as the dock could damage ships.
Earlier this year, the US Coast Guard were forced to sink an unmanned, derelict ship that was floating around in the ocean near the coast of Alaska.
