To me, the tree behind the fallen branch looks like ordinatry Gray Birch, which I usually call white birch. Did you mention Arrowwood? We have that here. Barry

The one behind your river birch fallen branch? Amazing. With the hophornbeam - euro or amer./birch. I'll have to get to see the buds and scratch the twigs (do river birch twigs have a fragrance like b. lenta?) Need some help with arrowood id. Do you have any? I wonder if we have any amelanchier in NYC forests. Too many species here!!! I think I will have a nervous breakdown when I finally go to the Appalachians.
