Likely black walnut; the image shows a small bark-covered log, so species-level identification is uncertain. Similar-looking alternatives include other walnut species or dark-barked hardwoods.

Grain Pattern
End grain shows curved growth rings; face grain is mostly obscured by bark. No distinctive figure or cut orientation is visible.
Color & Appearance
Fresh end grain is pale yellow-tan, unlike typical dark walnut heartwood; bark is gray-brown. Color may darken with oxidation, but the visible wood is insufficient to assess heartwood.
Hardness (Janka)
About 1,010 lbf (Medium), if black walnut.
Durability & Decay Resistance
Moderately durable; heartwood has some decay resistance, while sapwood is more vulnerable to insects and rot.
Value & Age
Roughly US$5–15 per board foot for ordinary kiln-dried lumber; this bark-on short log is not directly comparable and may have little value.

Common Uses
Furniture, cabinetry, flooring, veneer, gunstocks, turning, and carving.
Geographic Origin
Black walnut is native to eastern and central North America.
Workability
Generally machines and finishes well; sharp tools help avoid tearout, and predrilling is useful for fasteners.
Finish Recommendations
After confirming the wood and drying it, use oil, shellac, lacquer, or clear polyurethane; sand progressively and test finish on a hidden area.
Notable Features
Black walnut is valued for dark heartwood and often has attractive grain; neither feature is clear in this sample.
