Alaskan Yellow Cedar is a unique species in that it is very durable, much more so than even Canadian Western Red Cedar.
Found only on the Pacific coast of North America, Yellow Cedar is the hardest known cedar in the world. First used by the West Coast Indians for their historic Totem Poles and great war canoes due to its long durability. It grows in a band from Southern Alaska to Southern Oregon. It is one of the slowest growing trees in North America, 50-60 annual rings per inch are not uncommon.
It has high disease and decay resistance, making it the premium choice timber for cladding and roof shingles.
