I was a local in Valdez in 1969 and I believe it was herring that she was processing not salmon.  That was the time of the early herring roe fisheries in PWS and Japanese buyers were everywhere during the spring.  They were letting the fish rot and squeezing the roe out herring and dumping the herring carcasses in the bay.  Fly by night operators with Japanese money were setting up operations anywhere were they could find a dock to work on.   The operators could hire a bunch of kids and squeeze out the herring and be gone in a couple of weeks to a month. The amount of fish to process was limited and the season was short. 
 
The reason many of the locals do not remember much of 1969 in Valdez is that there is very few people in Valdez now that were around in 1969 and even less that were in the fish business.
