Paper birch.
When I was a kidlet, we'd spend three weeks in June in the Adirondack Preserve. The shedding sheet-bark of the paper birch has to be seen to be understood. The Boy Scouts understood how important was the curled sheets of thin bark..that one early figure made it into a poem:
First a curl of birch bark
As dry as it can be
then some twigs of soft wood
Dead from off a tree
Last of all some Pine knots to make a kettle foam
And there's a fine to make you think you're sitting right at home.
The rest of my post was lost in a web hiccup.
