Park Point Ferry

You might have seen the news story on a University of Wisconsin-Superior feasibility study of a water taxi between Barkers Island and Park Point. In what’s old is new again, I remember hearing of a ferry that used to run between Superior and the end of Park Point, when a community of summer cabins existed out there. But I can’t find any information on it, such as when it operated and where it docked on either the Superior or Park Point sides. Does anybody know where I can find any information on that?
