This is wood pulled from Southwest Louisiana Rivers that is branded on the end.  So we know all this wood was felled over 100 years ago for use in the mills of that day down river from where it was harvested.  The densest of these trees sank before they made it to the mill.  That means high quality wood today when it is pulled from the depths and milled and dried for use today.  Here are some pictures of this high quality, rare wood.
