Based on the whorl leave pattern I thought I'd found a Horse-Chestnut but the leaves are oppositely arranged. This was on the edge of a pond at a state park - not sure if it was planted or natural.
Not a Horse-Chestnut, But What?
Horse-chestnut is Aesculus sp.; that has palmately compound foliage with opposite arrangement along branches - not whorled.
I think you have a healthy happy Nyssa sylvatica there. Since this is a native tree in MA, it is probably naturally occurring.
Damn, I should have thought of that one! Especially with that bark which i think is distinctive (around here at least).
