For sure releventchair, a great fire starter. Another use I've read is making hats as this is like a felt type material...Very nice.
I'd be looking at it for a chunk to go in my flint and steel tin after seeing that it was dry.
I noticed a second small white birch where I hunted last year. 2 inch trunk maybe.
Of course a buck had to rub it instead of one of the thousands of alders..
