I'm posting pictures of oak and maple trees that I would like to know more about. The acorns tell me which ones are oaks. That may tell you how clueless I am. I'll post the tree and the next picture below it will be a close up of its leaves.

Here are two oaks close together. I don't feel like that are the same species.
The front tree's oak leaves are changing color first and its acorns are smaller. I planted both of them 28 years ago from a small pot that I could hold in one hand .
