Grain Pattern

Mostly straight, coarse grain with pronounced earlywood/latewood bands; the rough-sawn faces and knots obscure finer figure. Cut orientation cannot be determined confidently.

Color & Appearance

Freshly exposed wood is pale orange-brown to reddish tan, with darker knots and streaks; heartwood and sapwood are not clearly separable. Sunlight and oxidation deepen the tone over time.

Hardness (Janka)

660 lbf; Soft

Durability & Decay Resistance

Slightly Durable: heartwood has limited decay resistance; sapwood is vulnerable to insects and rot, especially outdoors when untreated.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$2–6 per board foot for ordinary construction-grade stock; grade, dimensions, and local market change the price.

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 estimated from this rough-sawn, weathered-looking surface; age of the tree and time since milling are unknown.

Common Uses

Framing, sheathing, beams, doors, millwork, and some furniture or flooring.

Geographic Origin

Native to western North America, especially the Pacific Northwest and coastal/interior mountain regions.

Workability

Generally machines and glues well, though knots, resin, and alternating growth bands can cause tearout or uneven planing; predrill near edges for fasteners.

Finish Recommendations

Sand progressively and use a compatible sealer, oil, varnish, or polyurethane; seal knots if resin bleed is a concern.

Notable Features

Strong, relatively lightweight for its strength, with conspicuous growth-ring contrast and frequent knots; may have a resinous scent when freshly cut.
