Grain Pattern
Straight grain with a tight, vertical/quarter-sawn growth ring pattern on the end grain and subtle cathedral arching on the face grain.

660 lbf (Soft)
Durability & Decay Resistance
Moderately Durable, with good resistance to weathering but susceptible to insect attack if left in contact with ground.
Value & Sustainability
- Estimated Market Value
- 3.00 to 6.00 USD per board foot depending on grade and vertical grain quality.
- Wood Age Estimate
- Estimated to be several decades old based on surface oxidation, patina, and weathering.
- Sustainability Status
- Not listed on CITES appendices, generally considered of least concern by the IUCN, widely available as plantation-grown lumber.
Common Uses
Construction framing, plywood, heavy timber construction, flooring, doors, and boat building.
Geographic Origin
Western North America, particularly the Pacific Northwest.
Workability
Generally easy to work with both hand and machine tools, though the strong contrast in density between earlywood and latewood can occasionally cause splintering or uneven planing if blades are not extremely sharp.
Finish Recommendations
Takes stains and finishes well, though a sanding sealer is recommended to prevent blotchiness; exterior applications benefit from UV-inhibiting penetrating oils or marine varnishes.
Notable Features
High strength-to-weight ratio, distinctive resin canals, and a characteristic pleasant, slightly spicy scent when freshly cut.
