Locally milled and kiln dried. This massive 14.5ft long old growth Fir slab has super tight grain and only a knot on each end, clear in the middle. This slab is super flat for being roughsawn and you'd lose very little thickness in the drying process. Has some minor splits on the ends and some checking but pretty minimal for the size of the slab. Tapers in width from 27" to 30"
