From the small size of the nuts, I'd say Allegheny Chinquapin (Castanea pumila). It's certainly not one of the culinary Chestnuts (Sweet, Chinese, or American).

Chinquapin or perhaps chestnut oak.

Oak, logan???

Bur Oak?

Come on folks;-) I've never seen a Chinquapin in my life but even I can see that it's got to be some kind of Castanea. Look at the fruit. Look at the leaves. Look at the remains of the inflorescence. All miniature versions of Castanea sativa sweet chestnut.

There is a small grove of chestnuts in Prince William County, VA. We were quite astonished to find them. Congrats on your find, Sam!

I would say Chinese chestnut or a hybrid....the leaves are too short and stubby to be fully American

Here's the nuts, unlike chestnut only one nut per bur.

I have considered ordering a few before, but everything I have ever read about them says they like dry sandy soil, which I don't have.

No doubt they are Allegheny Chinquapins assuming they are in a native stand.

Sam, were the nuts ripe? Did anyone taste them? I had some chinkapin nuts years ago that looked like that, and they were delicious.
