Grain Pattern

End grain shows tight, distinct annual rings and a small central knot; the face grain is not visible enough to determine cut or figure.

Color & Appearance

Pale tan to light brown, with darker growth rings; freshly cut appearance, so aging and luster cannot be assessed.

Hardness (Janka)

Janka about 620 lbf — Soft.

Durability & Decay Resistance

Slightly Durable; heartwood has some decay resistance, while sapwood is susceptible to rot and insects.

Value & Age

Estimated Market ValueNot an official valuation

Commodity-grade lumber commonly about US$3–8 per board foot; local prices and grade vary.

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 estimate calendar age from the photo; the visible rings indicate many growth seasons, but ring count is not a reliable age estimate.

Common Uses

Construction framing, beams, joinery, doors, flooring, and general woodworking.

Geographic Origin

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

Workability

Generally machines and glues well, though resin, knots, and alternating hard/soft growth rings can cause tearout or uneven planing.

Finish Recommendations

Sand evenly and use a sealer or compatible primer before lacquer, polyurethane, or paint; resinous knots may need spot sealing.

Notable Features

Prominent growth rings and a relatively high strength-to-weight ratio; the pictured end grain has a central knot.
