Geographic Origin
Western North America and Pacific Northwest
Workability
Generally works well with both hand and machine tools, though the pronounced difference in hardness between earlywood and latewood can occasionally cause uneven planing or sanding
Finish Recommendations
Takes stains and finishes well, though a pre-stain wood conditioner may be necessary to prevent blotchiness on the softer earlywood; polyurethane, varnishes, and penetrating oils work effectively
Notable Features
Known for high strength-to-weight ratio, distinctive resin odor when freshly cut, and pronounced growth rings contrasting earlywood and latewood
