Mighty Oak

We planted this tree in the front yard twenty years ago.  It was one year-old bare root stock.  A pencil-size twig.  And for the longest time we never thought it would amount to anything.

It's grown into a handsome young oak tree.  Further evidence of its maturation, it is bearing a sizeable crop of acorns again.  And if history repeats itself, when they ripen they'll barely last a week as the critters will hoover them up in short order.

The species has been forgotten so I asked a forester pal if she might ID the tree for me.  She is confident that it is a Northern Pin Oak (Quercus ellipsoidalis) commonly known as Hill's oak.
