White Oak (Witness Oak Jr.)
55 Fairview Avenue, Marietta PA
This tree (photo not yet available), now reported to be approxi- mately 100 years old, was grown from an acorn of the Donegal Witness Tree [see www.lancastercountytrees.org/donegal-witness-tree]. A second, younger offspring of the Witness Tree is growing on the Donegal Church grounds (see separate entry).
This amazing species contains protective cellular structures (called tyloses) that make the wood water- and rot-resistant. White Oak is thus used by coopers to make wine and whiskey barrels, and also in years past by shipbuilders.
