Wood: Very important; sapwood white to yellow; heartwood yellow to red; growth rings very distinct; used for high-quality lumber and plywood.

General: Native to the Pacific coastal states and Rocky Mountain states, including Utah.  Not a true fir.  Very valuable western timber tree.  Intermediate shade tolerance.
