For a forester in Pennsylvania, finding a red oak tree with a circumference of about 26 feet and a height of 120 feet is about as likely as seeing Bigfoot. But a giant does exist just beyond the fields of a Bell Township farm, rivaling some of the largest red oaks in the state, according to preliminary measurements. And it probably has been there for 400 years. Tom McQuaide of Torrance, a forester with Pennsylvania Forest Management, is in the process of submitting the tree’s measurements for inclusion in the Champion Trees of Pennsylvania, a registry of the state’s largest trees measured by several factors, including height and girth.
