23+ feet "wormy" White Oak. (larvae stopped eating it over a century ago). Pictured with flat side down.
8 inch nominal diameter, flattened on one side. Whitewash over bark. Shrinkage cracks run the length of it. Still structurally sound, but cracks and worm holes will reduce yield as flooring material.
Extremely dense, close-grained. Dovetails
indicate that it was originally used in a 19th century barn which was dismantled at the turn of the 20th century. Beam reused in a new barn. Finally removed from service in the 1990's and kept in dry strorage, supported on blocks ever since.
By counting rings, tree was about 70 years old when felled. (A young pup!)
