Sunken cypress is pulled from the great southern swamps.  It was either harvested or just fell in the swamp and has sat in the anaerobic conditions under the water for a century or longer.  To the extent that the logs were originally cut by man, they were axe cut.  There they sat for over one hundred years, absorbing the dark minerals of the swamp.  It is all old-growth material, tight grain and richly colored.

But the colors vary considerably from rich red and golds to the green and browns absorbed from the swamp.
