Does anyone know of a marine contractor, or a drilling and blasting outfit, that could drill holes in these rocks and split them up using expansion agents, rock-splitters, etc.?
I was going to try to expose the rocks during the winter and drill holes for an expansion agent, but the lake was too high and the ice too thin this year!

I watched one marine contractor "winterize" his steel barge by tying up to his next shoreline jobsite and filling the hull with water. In the spring, he just pumped it out and went on with his work there.
If your marine contractor removes the excavator and empties his hull, he can put a "necklace" of chain under the boulder and raise it off the bottom by pumping out the hull. He could then move it to deeper water.
(Or to my place—I could use a boulder to break up wakes.)
