Under several different names, what I call "Fatwood" or "Fat Lighter" is rich in resin and used for fire starting. It usually comes from the stumps of old dead pine trees where the resin continues to flow and accumulate creating a very hard/solid core. In most cases, the stump rots away but the resin core remains. I'm thinking that spruce is loosely in the pine family and am wondering if their stumps produce fatwood. Has anyone had success finding fatwood in Alaska?
