Comments:
2022 update: The Army Navy Country Club is very proud of this tree and has installed a nice interpretive plaque with its designation. The tree is completely healthy and is growing in the open. This would explain why the tree has increased in girth over the last 10 years relative to the two City of Alexandria Quercus marilandica in more shaded conditions. The large size of this tree for the species indicates that it contains a bit of Quercus velutina, a conclusion that very much occurred to me 10 years ago when first measuring it. However, leaves, buds, and fruits consistently and strongly place it as mostly Q. marilandica, so it is more than fair to keep it as such in the big tree register.

2012 update: Old age specimen growing on high dry ridge of golf course property along side of road. Appears to be part of original flora of site and is healthy. No known historical significance. Measured by Greg Zell and Rod Simmons, circumference of 122", height of 77', and crown width of 72'. Total of 207 points.
