Grain Pattern

Mostly straight, with visible growth-ring bands and a few knots; the broad face appears flat-sawn. End grain is not visible, so ring structure cannot be confirmed.

Color & Appearance

Pale peach-tan to light brown with darker streaks and knots; likely weathered or dirty. The image does not clearly show heartwood versus sapwood or luster.

Hardness (Janka)

About 660 lbf Janka; Soft.

Durability & Decay Resistance

Slightly Durable: heartwood has some decay resistance, while sapwood is less resistant; not reliably weather-resistant untreated.

Value & Age

Estimated Market ValueNot an official valuation

Rough construction-grade stock is commonly about US$2–6 per board foot; grade, region, and dimensions affect 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 determined from the photo; surface discoloration alone does not establish age.

Common Uses

Framing, sheathing, general construction, doors, and some furniture or flooring.

Geographic Origin

If Douglas-fir, native to western North America, from British Columbia through the Pacific Northwest and into the western United States.

Workability

Generally machines and glues well; resin, knots, and uneven growth can cause tearout or rough planing. Pre-drilling near edges helps limit splitting.

Finish Recommendations

Clean and sand, then use a compatible sealer and exterior-rated coating if exposed outdoors; test stain first because absorption may vary.

Notable Features

The image shows a weathered, knotty softwood board, but no distinctive scent, resin, or acoustic traits can be assessed.
