Thank you Elaine! Below are some answers to your questions:
Do you know what kind of tree it is? - I'm not sure what kind of tree it is. I tried doing some digging online with no luck.
It looks to me as if this tree is growing lots of healthy new branches down below the affected trunk area. Does the bark always look like that? - The bark is fairly dark everywhere else. The tan areas are just in the affected area.
Could you possibly cut or scrape off a couple and get a closer picture of them? - will do!
Thanks again for your help and for the warm welcome.
-Nate
