Dennis, these are wonderful - I can not believe the clarity and colour at over 100ft - we always have thought of the Great Lakes as probably polluted but in fact they are much clearer than any Scottish loch would be (go down a few feet and the water often becomes deep peat-brown-red).
Back around 1993 we set up a project to do a book called 'The Waters of Scotland' with our friend Lawson Wood FBIPP FRPS who was/is one of the best dive photographers around. We had already done the layout and editing for his book 'Undersea Britain' . The idea was to dive into river pools, lochs, harbours, inshore, canals, old mine working cave dives - everywhere - and also to use external landscape images. Lawson decided to sell up his holiday park and hotel business, and went to the Cayman Islands where I believe he still owns or runs a dive school - gave up on the cold water stuff!
Since then, I have seen an 'Underwater USA' book produced but I do not remember the images being as good as yours.
I am humming 'The Wreck of the Edmund Fitzgerald' in my head now but unfortunately (maybe fortunately for others) I only know the first two verses
