Alaskan Yellow-Cedar (AYC) is a species of cypress grown on the west coast from Oregon to southern Alaska in the higher elevations. AYC is known for it's natural beauty and strength. It is a slow growing tree with grain so tight that it can require a magnifying glass to count the growth rings. AYC is a popular choice for outdoor projects such as roofing, siding and decking due to its workability and decay resistence.
