SEATTLE (AP) - Rough seas and a dangerously swollen stream are keeping tsunami debris experts from reaching a dock that washed ashore on a remote beach in Washington.
It's likely that the large dock is debris from the March 2011 tsunami in Japan.
A spokesman for the Washington state Marine Debris Task Force says state and federal representatives got within 200 yards of the dock Thursday but the crew couldn't cross a normally passable creek that was running high and fast.
Team members plan to try again Friday if weather permits. They hope to verify the dock's origin, measure it and inspect it for invasive species.
The Coast Guard spotted the dock Tuesday on a wilderness beach in Olympic National Park. The area can only be accessed by primitive trails across rough terrain.
Officials say the dock appears to be similar to a Japanese dock that washed ashore last June in Newport, Ore. That debris was cut up and removed.
