Grain Pattern
Concentric end-grain cross-section showing distinct, tight annual growth rings with dark latewood and light earlywood bands, displaying slight end-grain checks and checking patterns radially outwards.
Color & Appearance
Warm reddish-brown to orange-brown heartwood with a medium luster, displaying pronounced contrast between light yellow-tan earlywood and reddish-brown latewood rings; darkens with exposure to light.
Hardness (Janka)
620 lbf (Soft to Medium Softwood)
Durability & Decay Resistance
Slightly Durable to Moderately Durable; susceptible to insect attack if untreated, moderate resistance to decay when dry.
Value & Sustainability
- Estimated Market Value
- $3.00 to $6.00 per board foot depending on grade, size, and clear figure quality.
- Wood Age Estimate
- Estimated tree growth age of approximately 40 to 60 years based on ring count in the end-grain slab; finished piece likely shows several years of surface oxidation and utility wear.
- Sustainability Status
- Least Concern (IUCN), widely available from sustainably managed FSC-certified forests and commercial plantations.
Common Uses
Structural timber, heavy construction, butcher blocks, cutting boards, flooring, millwork, plywood, and posts.
Geographic Origin
Pacific Northwest, Western North America (coastal and inland regions).
Workability
Works well with machine and hand tools; sharp edges required to prevent tearing in soft earlywood rings; glues, holds screws, and finishes reliably.
Finish Recommendations
Food-grade mineral oil or beeswax for cutting surfaces; polyurethane, lacquer, or penetrating oil for furniture and decorative display.
Notable Features
Distinct resinous, sweet pine-like aroma when cut; prominent growth ring contrast creates strong visual rings on end-grain cross-sections.
