Armed with that information, I was able to look it up online and learn more about it and confirm what he told me. It is, indeed, a Chestnut Oak (Quercus montana) which is a tree that is common in the eastern part of the US, from where @bluefinstudios lives, through the area where @sgt-dan resides, down through where @enginewitty lives, and then over to where I am!
The bark of the Chestnut Oak trees is heavily ridged and thick; in fact, it has the thickest bark of any other oak tree species in eastern North America. This thick bark also contains a large amount of tannic acid, making it a highly sought tree for the tanning process. [source]
The leaves are quite pretty when backlit by the sun as one is looking up into the tree.
Other color is prevalent in other patches of my yard, which is delightful! I have been sick the past couple of weeks, though, so have not felt like getting out and driving around, so I might be missing some of the best color this season. But, I will enjoy what comes this way while it is here!
Besides a few photos that I snapped around the yard in the last day or so, like the ones in this post, I do have many other photos from autumns-past. Some have never been shared, some have, but I have the new photo processing technique which I devised earlier this year, so even previously-shared photos will have a new look!
