Hackberry Bark

We've been cutting down a few trees around the house.   This is the bark from a hackberry tree.  

I could look at it all day long.  Click the pic for a larger view.

Cool Bark

I've said again and again that I'm not so great at identifying trees by their bark.   

So it's kind of frustrating when I see really cool bark like this and I can't figure out what kind of tree it is.





Compound this with the fact that most of these trees were cut down by the power company a couple of years ago, so there won't be any leaves in a few weeks to help me out.  [I'm good with the leaves!]   So if you guys know what this is, please shout it out.  

It's so pretty how the decaying bark marked the wood underneath.



Here's a bigger pic of the log.    I'm guessing dogwood, but that's only a guess.   The log was maybe 10 inches diameter.
