Most likely Black Walnut; alternatives include Butternut or another mature walnut (bark-only identification is uncertain).

- Hardwood (deciduous)
- Origin
- Eastern and central North America, especially the Midwest and Appalachian regions.

Grain Pattern
Not visible from bark; walnut lumber is typically straight-grained, sometimes irregular or figured.
Color & Appearance
Interior color cannot be assessed. Black walnut heartwood is chocolate brown to purplish brown, with pale gray-white sapwood and moderate luster.
Hardness (Janka)
1,010 lbf Janka; Medium.
Durability & Decay Resistance
Moderately durable to durable; heartwood has useful decay resistance, while sapwood is less resistant. Insect resistance is variable.
Value & Age
Rough walnut commonly ranges about $8–$20+ per board foot; figured or exceptionally wide stock may cost substantially more.
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 tree appears mature, but sample age and lumber age cannot be estimated reliably from bark alone.
Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, carving, and fine interior millwork.
Geographic Origin
Eastern and central North America, especially the Midwest and Appalachian regions.
Workability
Generally machines and hand-tools well, sands and glues reliably, and holds fasteners well; interlocked grain can cause localized tear-out.
Finish Recommendations
Use a clear oil, shellac, lacquer, or polyurethane after thorough sanding; water-based finishes may accentuate color variation or raise grain.
Notable Features
Distinctive dark heartwood, attractive natural luster, good dimensional stability, and occasional curly, crotch, or burl figure.
