Locally milled and kiln dried. Mostly Fir, some Hem and Spruce mixed in. "Teredo lumber" is milled from salvaged boom logs that have seen 30-70 years of use on the waterways of the PNW to transport lumber from forest to mill. The teredo clam likes to call these logs home by burrowing deep and creating unique and intricate patterns in the wood. Most of these boom logs were old growth. Beautiful wood that makes a statement. All lumber has been milled, cleaned, and kiln dried out on the Olympic Peninsula. Lengths vary, most from 4-8'. Please note, this is a bulk item and can not be put on hold.
