Note that I found this material around Light Buoy #12 and also smaller amounts about 800 feet away at the black spar buoy off Garnet Point to the northwest (as you look for example towards Poplar Is.).

The material can be found in sheets, some I estimated at 4-5 feet long or so, as I could put my hand under the edge and lift up, picking up perhaps 2 square feet or so before it broke off. Most often it is found in smaller sections, or as the piece I took home and photographed that looks like a cinnamon bun.

As I said the material is not very heavy at all, prob. accounting for it's brittleness. How this ended up on the lake floor in slabs/sheets is another question. Hard to believe it was poured hot into the water. If that was done you would think it would pile up like a volcano of sorts before cooling not flatten out.

It would be interesting to have it analyzed.
