Locally milled & kiln dried. These have amazing bore channels that come from the notorious teredo clam. These saltwater clams spend their entire life span in these logs creating their tunnels, that rarely intersect. The raw stock logs (before milling) were originally used as boom surrounds in antiquated timber transport. These logs used to be left to rot in coastal towns before our supplier took it upon himself to repurpose them. Very unique stock, teeming in NW history. Dimensions listed are for set combined. The 11th board is extra and allows you to switch up the pattern to the side you like most.
