Hello, Bo! Welcome to the Native Tree Society!
I am a fellow easterner (of Massachusetts) with an interest in old and big trees. I had a chance to visit the Carlisle Pines last month. That hemlock that you measured is quite a tree, huh? It's a shame that the hemlock wooly adelgid has gotten the best of it. Just next to that old tree is the tallest of the Carlisle Pines at 124.8 feet tall (see picture below). There are other old pine trees in there, but none as tall (that I or others have measured). As far as wider pines in those woods, I did measure one with a circumference of 10.88 feet working towards 120 feet tall. My search was by no means exhaustive, so if you do find some other nice, big ones in there, please report on them!

I use this website to share my big tree finds and to read about what other folks are finding in other parts of the country and world. I've even met the humans behind some of the usernames you see on this site, as Bob Leverett kindly introduced me to the tall trees of Mohawk Trail State Forest and others in their fan club. The more time I spend out in western MA the more it becomes clear how rare old and tall trees and forests are in the eastern portion of the state. I've spent some time tree hunting in Concord, specifically at Punkatasset Hill. I found some white pines over 130' tall, though not as "girthy" as the Carlisle Pines. I've heard that Estabrook Woods has some good, old trees. It may not be old growth, but it is nicely-maturing second growth. If/when you do come across some trees that meet your criteria for being interesting, do share pictures and a story with us!
Happy tree hunting!
