Goby Walnut purchases logs from Oregon and Washington. Logs must be a minimum of 24" in diameter and 8' long, free of steel inclusions. Please inquire if you have logs for sale. If you are selling Black Walnut trees outside of the west coast area, our advice to you is to call your county extension service and request the name of a forester who can give you names of timber buyers. Get more than one bid. Selling single trees may be difficult. Good luck.
