Pyramids of Rock Lake

[FreediveWI]

I dove them about 12 years ago. THey are mostly rock piles onthe bottom. Nothingis marked and not much to see.

The lake itself is pretty much of a mess. My dive buddy and I were freediving in there last fall and we couldn't even see to the end of our spearguns. The bottom was a very soft mud/silt mixture.

The lake is infested with Euroasian milfoil which has been accelerated by the carp population.

If you really want to dive it try contacting Dr. Richard Boyd at Global Manufacturing in Milwaukee. He has done some research into it and might have numbers for you.

One of the people that had done a lot of side scanning in there, Clark Willick, died last year. I don't know what happened to his documentation. There are a few books out on the subject. They start off normal, but kind of go off into left field by the end.

Hope this helps,

Jon
