I don't know what this log is

thanks for explaining all that, wish i would take the time to study a bit more.

That makes me feel so smart!!  I had looked at the rings and though, "black gum doesn't have rings that you can see very easily."  I didn't know why, but you have taught me something.

Now, about the bark. 

That is one major characteristic that points to ash, besides the bark.

What would you designate as an Ash bark.   Gum is more of "Woof woof " and I picture Ash as being more of a "yap yap".

Hey Tom, I think Ash barks come in a wide range of sounds from near silent to loud and rauccous.

[WDH]

Yep Lee,  ash bark can be quite moody .

Ash bark has ridges that can run together and make a diamond pattern sometimes and at other times, they do not form the diamond ridges.  It can be variable.  In fact, there can be a few feet of bole with very distinct diamond ridging, then the bark breaks up into blockly knobby squares and rectangles.  Also, there is a green lichen that loves ash bark, and it is visible in the pic.

That bark is also typical of the many Bur Oak we have here. I just misjudged the width and depth of the ridges and valleys when I saw the first picture. Bur Oak bark has much coarser ridges and deeper valleys.

Since I had already typed that guess, I just left it but also noted it did appear more like Ash. The end grain picture with the pronounced rings made it almost sure it was Ash and not Bur Oak.

Bur Oak is also one of the most dense hardwoods we have, so that description of very hard was another misleading clue. Bur Oak can be so hard that sometimes sparks will fly when you cut it with a chainsaw.

I've seen white ash with different bark from one area to the next. Some areas have ash with diamond shaped ridges and deep furrows and some less furrowed, but more of a flaky texture. It might be the different between white and green, I am mostly familiar with black and white ashes. Black ash bark is corky in my area and 99% of the time found in swamps and lowlands. White ash doesn't like swampy ground. In my area there is tons of white ash second growth, now a ways north of here the only ash I see is black ash.  Seems to me white ash is mostly restricted to the best growing sites in my province and that's mostly in west central and south central NB. We call your green ash, red ash because it has bark sometimes with a reddish tinge to it.

Ditto to WDH's description.
