Grain Pattern
Broad, mostly straight grain with mild cathedral and irregular swirl around knots; appears flat-sawn, with coarse-to-medium texture.

Brown to gray-brown heartwood with subdued lighter streaking and very little visible sapwood; likely oxidized and weathered, reducing contrast and luster.
Hardness (Janka)
1,010 lbf Janka — Medium.
Durability & Decay Resistance

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 slab’s age cannot be determined visually; surface oxidation and wear suggest years of exposure, not necessarily old timber.
Common Uses
Furniture, cabinetry, flooring, architectural slabs, gunstocks, veneer, turning, and decorative panels.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachian regions.
Workability
Generally machines, sands, glues, and finishes well; knots, checks, and localized grain reversal can cause tear-out. Pre-drilling is advisable.
Finish Recommendations
Flatten and sand progressively, then use dewaxed shellac, lacquer, oil, or polyurethane; seal end checks and test finish absorption on the weathered surface.
Notable Features
Distinctive walnut color, attractive knot figure, moderate weight, and good dimensional stability.
