Cool pic, is that a cemetery stone in the back? A private cemetery?
Uh...of the two, elm is more likely to be multi boled, your tree is most likely not a hickory. They tend to have a very straight central leader stem. Rock Elm might be confused with hickory.
Sometimes the tree is cut and multi stems grow back. Copiced trees.
The thing with Elms is they are fighting extinction along with White Ash. If the tree is healthy its kind of a sin to cut it down.
But I cant say positively that its an elm because its really healthy looking.
I sometimes rely on the bug eaten appearance of Elm to ID it. Missing bark and bug holes.
I have a small cemetery on my property. A group works with the town to identify these cemeteries and put some split rail fence up and keep an eye on them. I want to take some trees down around it to keep it clean. The youngest stone is from 1848, I assume the one's that cant be read are even older.
I wouldn't take it down if it was in the middle of the woods, but it has to go.
