Unaffected by Dutch elm disease, this American elm lives in the very well-labeled 50-acre Thain Family Forest, "the last remnant of the 17th-century woodlands that once blanketed the region, the same woods in which the Lenape Indians hunted, with some of the same trees standing."
I’ve also seen American Chestnut in the Thain Forest. Only a foot or two tall, and about to succumb to the chestnut blight.
