Thanks guys. I walked back down there to grab some leaves. Got to use my new pike pole in fact.
It's about 10ft up to grab the first ones and I probably had "
Eclipse Anxiety" at the time of looking at them the other day... Where that tree sits, the upper leaves get sun all day but getting a picture underneath of the boughs for the trunk/bark is too dark to make a useful ID. It is absolutely covered in bees as well. They behaved well but I did make a hasty retreat.
I
was wrong about the leaves though-

That does change what the tree is but it probably doesn't change my novice train of questions though lol.
