I'm trying to establish an approximate age for this large Sycamore tree growing on historical property in Wheeling, WV. It is about 7' dbh and is being taken down due to damage incurred many years ago. There are huge branches growing just below and putting a lot of weight on the damaged area. As I type this, it is being removed. Some have said the tree could be as much as 300 years old. That would make it a sapling when the area was settled in the early 1700s. The owner of the property at the time was Lydia Boggs Shepherd who convinced the Feds to re-route Route 40 so it would pass closer to her home. They have already removed some very large branches from the left side in the photo.
