Question
I was camping in Savoy State Forest in Massachusetts recently and came across a tree that, when I snapped a small branch, the inner wood smelled like Bengay. The leaves didn't seem to have a scent though. It was an older tree, and it had roughish bark  that could be peeled like birch. Can't seem to find out what kind of tree this is.

Answer
I checked with one of my fiends who is an expert in tree ID and this is his answer.
"Don't know of any southern trees that do that.  Couldn't be a camphor since they could not handle the cold and the leaves are very aromatic.  There is a tree common to the Sierras called California laurel that smells like bengay and is real strong smelling to the point it will almost knock you down.  Don't think that is it since it only grows out west but it might be a relative, like some kind of true laurel.  Without the leaves or fruit, afraid I can't be of much help."
Sorry without a picture of the leaves I can not help.
You might call the Mass/ State Forestry agency and ask them since it was on their lands. Here is their e-mail address  [email protected] <[email protected]>

Or here is the contact page of the  web link to the Mass. Forestry I think Savoy is in the Western region:
