Randi, the way this tree is growing reminds me of the Live Oak that grows in the coastal region of the southern US. This is a very impressive tree and one that would have attracted me as a kid because of it easy access for climbing.
A tree similarly shaped was my favorite as a kid. I built tree houses and ladders into the limbs all through this tree. It was a Mulberry tree that was cut down years later when I was grown. I heard the man that had the task of cutting the tree was cursing me with every cut. I had probably put 100 lbs of nails in that tree, over the years, and this managed to repeatedly dull his saw.

This is the Southern Live Oak Tree.
