Also known as white spruce locally. A tree of the Rocky Mountains but with a natural range extending from British Columbia southward through the interior mountain ranges of Oregon, Washington, Montana, and Idaho to Arizona and New Mexico. A few isolated groves occur in Shasta National Forest, California. Essentially a tree of higher altitudes and, although covering a wide range, found in large stands only locally. Maximum size 5'x150', but averages 2-3'x120'. Usually knotty. The wood is light, soft, and close-grained, though not strong. Used for construction lumber, boxes, mine props, poles, and paper pulp.
