Grain Pattern
Generally straight and plain with a coarse texture. Visible flat-sawn cathedral patterns on face grain with a prominent growth ring contrast between earlywood and latewood.
Color & Appearance
Heartwood is typically a yellowish-tan to reddish-brown, while sapwood is a paler cream or yellow. Color tends to darken and become more reddish with age and UV exposure.
Hardness (Janka)
660 lbf (Soft)
Durability & Decay Resistance
Moderately Durable; heartwood is resistant to decay but susceptible to insect attack.
Value & Sustainability
- Estimated Market Value
- $2.00 - $5.00 per board foot depending on grade (Vertical Grain commands a premium).
- Wood Age Estimate
- Modern lumber, likely 1-5 years post-processing based on lack of significant oxidation and presence of mill markings.
- Sustainability Status
- Not listed on CITES or IUCN Red List; widely available with FSC certification; considered highly sustainable in North America.
Common Uses
Heavy structural lumber, construction framing, flooring, veneer, plywood, and trim work.
Geographic Origin
Western North America (Pacific Northwest)
Workability
Generally easy to work with machines, but requires sharp tools to prevent tearing. Can be difficult to stain evenly due to density differences between earlywood and latewood; glues and finishes well.
Finish Recommendations
Clear polyurethane or lacquer to preserve color. A sanding sealer or pre-stain conditioner is highly recommended if staining to avoid blotchiness.
Notable Features
Distinctive resinous, sweet scent when worked. High strength-to-weight ratio for a softwood.
