The link below will lead you to a really old (1948) video of Morro Bay. It is of poor quality because it is from an 8mm film that had a film speed of 7. The photo below is in the video toward the end. It is a wall of abalone shells that were stacked near a packing plant--perhaps Brebes. I seem to remember that many were removed to a new location. However, they were great souvenirs.
