Color Description
Light brown to reddish-brown heartwood with lighter yellowish sapwood; darkens significantly to a deeper orange-red or grey-brown with age and UV exposure

Market Value & Sustainability
Estimated Market Value
$4.00 - $7.00 per board foot for select grades
Wood Age Estimate
30 to 50 years based on surface oxidation, water staining, and the accumulation of superficial grimy patina
Sustainability Status
Least Concern (IUCN); widely available with FSC certification; considered highly sustainable
Workability
Generally easy to work with tools; planes and glues well, though earlywood/latewood density differences can cause uneven staining or sanding and splitting when nailing near edges
Notable Features
Distinctive resinous scent when freshly cut; high strength-to-weight ratio; high resin content which can bleed through finishes
Finish Recommendations
Penetrating oils or clear polyurethane; requires a sanding sealer or wood conditioner to ensure even color absorption if staining
Identification Confidence
High; the prominent latewood bands, reddish-orange undertones, and linear texture under wear are characteristic of Pseudotsuga menziesii
