What kind of oak tree?

This is an oak tree. He hasn't produced acorns yet. He's about 15 years old and near 20 feet tall.



Here are leaf pictures, top and bottom.





This is momma tree  50 feet tall? About 3 feet in diameter.

Why do I give a damn about his name? I am planting a copse. I want wood that will be good for firewood and timber framing. Think sheds, animal shelters. I've been reading.... Red oaks are weaker than white oaks. Who knew? I wanna tip the scales toward success. I have maybe 50 seedlings popping up.

Oak species are usually divided into two broad categories: red oaks and white oaks. Red oak species have bristly or pointed leaf tips and lobes, while members of the white oak group have rounded leaf tips and lobes.  Here is a guide from the University of Tennessee to the oaks of your state featuring some nice photos and pointers for identification:

I can't tell which one you have, but I hope this helps!

The quickest way to distinguish between them, is to look at the end grain. Red Oak pores are
larger than White Oak. (Interesting Fact - If you place one end of a piece of Red Oak in soapy
water and blow through the other end, you will actually see bubbles!)

From here.

Weird. I wonder if this would work with greenwood, or just dry?

Has your oak tree produced flowers and catkins?

Does the oak tree loose its leaves in the fall?

Edit to say the tree looks like a Willow Oak.
