Grain Pattern

Mostly straight, vertical grain with prominent earlywood/latewood bands, subtle cathedral figure, and several knots; edge shows fibrous splintering.

Color & Appearance

Pale yellow-brown to tan with darker brown growth lines and knots; moderate luster. It typically darkens slightly amber-brown with age and light.

Hardness (Janka)

660 lbf Janka; Soft.

Durability & Decay Resistance

Slightly durable: limited resistance to decay, insects, and prolonged weather exposure unless protected.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $3–8 per board foot for ordinary clear/select material; reclaimed or exceptional stock may differ.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Cannot be reliably dated from the photograph; the weathered edge suggests prior exposure or handling, not necessarily old age.

Common Uses

Framing, beams, siding, doors, flooring, furniture, cabinetry, veneer, and utility construction.

Geographic Origin

Native to western North America, especially the Pacific Northwest and inland western mountains.

Workability

Machines and glues well, though resin, knots, and pronounced latewood can cause tearout and uneven sanding; predrilling is useful near edges.

Finish Recommendations

Sand evenly and use a conditioner or washcoat before stain; clear polyurethane, lacquer, or penetrating oil are suitable finishes.

Notable Features

Lightweight for its strength, aromatic when freshly cut, and characterized by strong growth-ring contrast and excellent structural stiffness.
