Grain Pattern
Straight to slightly wavy grain with prominent, tight growth rings featuring alternating earlywood and latewood bands, displaying a mix of flat-sawn cathedral patterns and vertical/quarter-sawn linear grain.
Color & Appearance
Light brown to reddish-brown heartwood with a distinct paler yellowish-white sapwood. Exhibits a warm amber patina from aging and light exposure with a natural medium luster.
Hardness (Janka)
660 lbf (Soft)
Durability & Decay Resistance
Moderately Durable, with moderate resistance to decay and insects.
Value & Sustainability
- Estimated Market Value
- 3.00 to 8.00 USD per board foot depending on grade, clear vertical grain vs knotty, and whether reclaimed.
- Wood Age Estimate
- Estimated to be 50 to 100+ years old based on the deep amber patina, accumulated surface wear, oxidation, and historical square or cut-nail impressions visible.
- Sustainability Status
- Not CITES listed, generally of least concern on the IUCN Red List. Readily available from sustainably managed forests and widely recycled as reclaimed lumber.
Common Uses
Structural framing, flooring, cabinetry, heavy timber construction, doors, window sashes, and boat building.
Geographic Origin
Western North America, particularly the Pacific Northwest.
Workability
Generally works well with both hand and machine tools, though the significant difference in density between earlywood and latewood can occasionally cause splintering or uneven planing if tools are not kept sharp.
Finish Recommendations
Accepts stains, varnishes, oils, and polyurethane well. A sanding sealer or conditioner can help achieve an even stain absorption due to the density variations between earlywood and latewood.
Notable Features
High strength-to-weight ratio, distinct contrasting growth rings, aromatic resinous scent when freshly cut, and excellent dimensional stability.
