This is some high quality, high resin, stinks of pine sol, waxy Pacific Northwest (Washington State) Douglas Fir (pseudotsuga menziesii) fatwood or also known as lighter. Fatwood is the naturally occurring result of highly flammable resin solidifying in pine wood. This resin impregnated wood will easily take a spark from a ferro rod, is waterproof, works at high altitude and in extreme temperatures. It is a must have in a camping or survival fire kit. Can be used to start the fireplace as a chunk will burn for 5 to 10 minutes. Even can be used as an incense. Fatwood was once used in the southern United States for turpentine tar production to seal the ropes on ships from moisture. The last photo with the lake is where the fatwood was harvested in the woods in northwest Washington State. Locally sourced, small batch harvests.
