It’s amazing to think about all the changes that have occurred since then. More than 100 years later, when the Seminary Memorial Plaza was built in the 1990s, the already huge white oak was showing sign of health issues. Root decay was becoming evident on the west side of the tree.
To protect against severe damage, a lightning arrester system was installed. Eventually a full risk analysis in 2014 gave it a high hazard rating, and the tree was scheduled for removal.
