While bottle diving the last few weeks in Maine I came upon an item that is too big to recever easily.
At about 50 feet in a flat, gravel area I spotted a 40" diameter mill stone. Ships used to use these as ballast and dumped them from time to time. It has the typical square center hole and is covered in pink and purple coralline algae. Supposedly there is a field of these things just off shore.
Anyway after the dive I went to an an old traditional mustard mill in town that still uses the old granite mill stones and asked them how much the item might weigh. Their response was close to a ton. I guess I'm not pulling that off the bottom anytime soon.
I checked on-line and old mill stone that size goes for about $4,500!
I know where a smaller on lies that might be a bit easier to retrieve.
