Value & Age

Estimated Market ValueNot an official valuation

Approximately $3–$6 per board foot for clear-to-knotty retail lumber, varying by thickness and grade.

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 sample appears recently milled; no reliable patina or wear indicates significant age.

Common Uses

Cabinetry, furniture, doors, millwork, paneling, painted parts, veneer, and small turnings.

Geographic Origin

Pacific Northwest and coastal western North America, especially British Columbia, Washington, and Oregon.

Workability

Cuts, planes, sands, glues, and finishes easily; soft fibers can dent, compress, or fuzz, and knots may tear or resist finish absorption.

Finish Recommendations

Use sanding sealer or conditioner before stain to reduce blotching, then apply lacquer, shellac, oil, or polyurethane. Clear finishes preserve its warm pink-tan color.

Notable Features

Lightweight, low-luster wood with subtle natural knots and excellent paintability; commonly resembles cherry when stained.
