Description
A large, softwood tree, Chamaecyparis nootkatensis, found in the Pacific Northwest. Alaska cedar belongs to the cypress family, but is called a cedar because of its aromatic smell. The yellow wood has an even texture and a fine, straight grain. Alaska cedar is used for boat building, veneers, lumber, cabinetry, closets, and chests. It is very durable and has the advantage of being resistant to insects and rotting. Yellow cedar fibers, carefully prepared from strips of the inner bark, were woven, often mixed with wool, into blankets and cords by the Salish, Kwakiutl, and Tlingit tribes (King and Hartley 1979).
