Reported by Jeff Christner: “Found some interesting items today at the Mussel Rock cleanup. Empty sharps bin with a City/County of San Francisco sticker on it. I wonder if this is related to all the needles that washed up last week on Esplanade Beach. Also three suspect 2011 Japanese tsunami debris items. Two are suspect due to the wear of the plastic, one with similar wear along with markings. Most of the markings are missing but I think “高橋” is the first part of the name of Takahashi Seiki Co., Ltd., a plastics molding company, which would make sense. Neat markings, but nothing unique to enable it to be confirmed as tsunami debris.”
