The height of this dock above the waterline was about 7 or 8 feet, for a sense of scale. Here we see where the I-bars were ripped away from the rebar in the dock's interior structure. In addition to the damage wrought by the tsunami, note the ubiquitous attachment scars where marine organisms colonized the surface. One of the first things done after the dock landed was to scrape, scour and burn off these organisms, some of which may pose an invasive threat to our waters. I'm skeptical of the efficacy of this move, but no harm in trying, I guess.
