I’m trying to identify a tree in my yard

Question

This is a very fast growing tree that has a relatively smooth bark, similar to that of a golden chain tree, with small horizontal marks along the entire trunk. It produces golf ball size fruit that is very hard and horrible to eat. When new branches come out, they are covered with thorns about 1″ long and very sharp. The leaves are all individual and about 2-3″ when mature, dark green with lots of veining and a very subtle saw tooth edge. The leaves also curl. I would like to know what it is and if there is anything that I can make out of the fruit.

Answer 1

It may be a Washington hawthorn or some other kind of hawthorn.

Answer 2

Thank you, I'll do some research in that direction!
