Spruce, Engelmann
(Also known as white spruce, Arizona spruce, silver spruce, balsam, mountain spruce)
Softwood 23 lbs. per cubic foot, 1.92 lbs. per board foot
These varieties are described only to avoid confusion with the Sitka type of spruce. Grown mainly in the Rocky Mountain states, they are not suited to boat use due to softness, low strength, low resistance to decay, and lack of shock resistance. The sapwood and heartwood are hard to differentiate, and the wood is nearly white in color. It can be used in non-structural joinerywork, however, if not subjected to moisture.
