It's the Paper Birch found in northern and boreal woods. The bark contains natural resins that will ignite if it gets wet as the resin itself is water proof.

Don't remove bark from a live tree unless it's a true emergency. I carry a few pieces in my fanny pack that I removed from a downed log on the ground. Stripping bark off a live tree is unsightly and may eventually kill the tree as the stripped bark girrdles the tree. Especially trees near well worn paths. BTW, I went of the trail about 100 yards to collect from my tree, which had been blown down during a hard storm.
