Grain Pattern

Predominantly straight, coarse grain with prominent earlywood/latewood contrast; the torn surface obscures the original cut and any figure.

Color & Appearance

Pinkish tan to orange-brown heartwood with lighter cream sapwood; moderate luster, typically darkening slightly amber-brown with age and light.

Hardness (Janka)

Janka approximately 620 lbf — Soft.

Durability & Decay Resistance

Slightly durable; heartwood has limited decay resistance and is not reliably resistant to prolonged weathering or insects.

Value & Age

Estimated Market ValueNot an official valuation

Approximately US$3–8 per board foot for ordinary clear/select stock; rough or damaged material may be worth less.

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

Wood Age Estimate
Not reliably determinable from this image; surface oxidation and tool wear suggest seasoned or previously handled wood, not necessarily antique.

Common Uses

Framing, beams, siding, doors, furniture, cabinetry, flooring, plywood, and general construction.

Geographic Origin

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

Workability

Generally machines, sands, glues, and fastens well, though resin, knots, and pronounced earlywood can cause tear-out, fuzzing, or uneven sanding.

Finish Recommendations

Sand or scrape to a sound surface, seal resinous areas, then use penetrating oil, shellac, lacquer, or polyurethane; test for uneven absorption.

Notable Features

Distinctive resinous scent, strong light-versus-dark growth-ring contrast, good strength-to-weight ratio, and frequent knots.
