I have an idea...wondering what your thoughts are. In the middle picture it's growing between a different tree...it's the branch in the "middle"
Gosh im fighting to say cottonwood here. I just see a lot of that when the tree is significantly mature. It makes the bark look peeling.probably really not.
I'm thinking it's a red mulberry. It has a bunch of fuzzy things hanging from it that looks like it will mature into fruit. You can sort of see a few of them in the pic of the leaves. It's growing between what I believe is a huge elm and it's not doing well. I'm thinking of cutting it next fall for firewood if it's not basswood or alder.
Looks like the basswood we have up here anyway, though the leaves do look a little different. Not sure on how many types of hickory there are but it seems like the bark is shaggier on the ones ive seen.
redbud doesn't bloom like that, the flowers come before the leaves that looks more like basswood or catalpa if the leaves are the size of your hand
Basswood makes quick fires. It's quick seasoning, and burns clean. It splits pretty easily too I like it for shoulder season wood.
I have a lot of Basswood here, but firewood customers would be enraged if I sold it to them as such, along with Popil and high concentrations of Ash. It can be sold for logs, but does not pay much, and it is not qualified to be Mat Logs. It is kind of funny wood, super soft to saw into, but teeming with water so it does okay going to the paper mill since green, it weighs up enough to justify cutting it. I actually have some going to the paper mill today; not much, maybe a cord.
Back in my sawmill days we sold a lot of basswood. Furniture makers used it for drawers, it's light, fairly strong and takes stain good. I liked it because it didn't weigh much and was easy to stack. I spent many a hot day stacking Basswood while a guy graded it. That was a lot better than the days I spent stacking Oak!
