Whats the ladder from?

[PJK]

I'm not sure Doug.  Your best bet to find out about the ladder is Steve Daniel.  He wrote a book about different dive sites along the North Shore of Lake Superior.  He may have something written in his book about it.  I will check  when I find my book again.  I will most likely need to purchase another book if I can't find it.

Thanks for the question about the ladder.  One of us will most likely getting back to you on it soon.  Keep the questions coming.
