Grain Pattern

Predominantly straight, fine-to-medium textured grain with prominent latewood lines; flat-sawn face shows elongated cathedral features and knots.

Color & Appearance

Warm orange-brown heartwood with lighter sapwood and noticeable growth-ring contrast; typically darkens slightly to amber-brown with light exposure.

Hardness (Janka)

660 lbf Janka; Soft.

Durability & Decay Resistance

Slightly Durable; heartwood has limited decay resistance and is not naturally weatherproof, while sapwood is more vulnerable to insects and rot.

Value & Age

Estimated Market ValueNot an official valuation

Approximately $3–$8 per board foot for ordinary clear or knotty stock; premium appearance grades cost more.

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

Wood Age Estimate
The board appears relatively modern; surface patina and wear do not establish tree age, likely years to a few decades since milling.

Common Uses

Framing, beams, siding, flooring, furniture, cabinetry, doors, veneer, and general woodworking.

Geographic Origin

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

Workability

Machines and glues well, though resin, knots, and alternating earlywood/latewood can cause tearout, fuzzy surfaces, or uneven sanding.

Finish Recommendations

Sand evenly and seal knots with shellac or a stain-blocking sealer; use clear lacquer, varnish, or polyurethane. Test stains because earlywood absorbs unevenly.

Notable Features

Strong growth-ring contrast, characteristic resinous scent, good strength-to-weight ratio, and decorative knot/cathedral figure.
