Washington wildlife officials are testing samples taken from a 20-foot boat that could be debris from the Japanese tsunami to make sure it wasn't carrying invasive species or pathogens.

Ecology spokesman Curt Hart says the fiberglass boat was pulled from the beach Saturday and thoroughly cleaned at a maintenance service yard at Cape Disappointment State Park.

The boat was found beached at the park Friday. Hart says state and federal officials are still trying to determine whether it is debris from the Japanese tsunami, and will likely know more next week.

He says the boat will remain at the park for a week so the public can come see it.
