Fatwood is what you need to find, if you know where to look. At the base of dead trees or where the branches meet the trunk. It has an amber color and smells like turpentine, is hard to chop but lights even when wet. But I’m not an outdoor survivalist, any more than these guys apparently.
In the PacNW, its as I described. What you call “fatwood”, is what is called pitch wood. Same thing.
