Is that a gnome right of center in pic #1!!
I've looked at these photos long and, perhaps, a little too hard. I've got to go w/ "not quite right".
Now, I have seen rubs on trees that large before so it's not the size that throws me, but the edges seems very definite-less "rubbed" and more cut-particularly the second two photos.
It may be a broken tine?
Get a trailcam up if you can.
