Growing up in Georgia back in the 60's and 70's we called it fatlighter. We would wrestle it out of the ground from pine trees that died and rotted naturally. Once had a pile the size of a big wheelbarrow that we torched off at squirrel hunting camp. Kinda scared the crap out of us 4, 10-12 year olds. Big,hot fire,black smoke! Thought we might burn the woods down with that one.
2016, found a big,naturally dead fir stump on our place during property clearing for our house build. Smelled it before I saw it. Son-in-law was digging stumps, putting into piles and grading. I was watching him when I smelled it. Had him dig it out and set it aside. Still have about half of it. Gave most of other half away to friends.
I usually have in my pack: 3-4 sticks of that, some cottonballs soaked w/hand sanitizer, 12 waterproof matches (vacuum sealed) and a Maratac Peanut lighter.
I think when a pine or fir tree dies naturally and rots away above ground a lot of the pitch travels down the tree to the roots.
