These Photos are from North Coast Trail near Laura Creek July 2012 Its not immediately obvious that there is lots of this insulation material on the beach. You could fill several garbage bags quite quickly. Its a disaster for wild life that chews on the stuff. Of course there is no way to determine if the materials in these photos are a result of the tsunami in Japan. The junk could have come from a thousand different places. I just don't remember seeing so much of it when I first hiked the trail just after it opened a few years ago.
