I mentioned "The Tree" earlier.
It was a forty-foot maple resting on a big iceberg. From what I could see from my boat (back from the edge of a thick ice sheet), it had sunk in a rocky area close to shore.
There was also a leftover three-foot section of oak dock piling, cut at an angle (to sharpen the piling prior to being driven). Shaped like a giant door stop. It was waterlogged, incredibly heavy, and I had to drag it over the gunwhale with effort.
It dried out on the dock, has been split, and some of it has been converted to heat in my wood stove.
Oh yes...I still have that new mooring float that floated by after ice-out. Name it and claim it.
