Grain Pattern
Mostly straight to irregular, coarse-textured grain; the photographed rounds are cross-cut, so end-grain pores are only partly visible.
Color & Appearance
Fresh heartwood appears yellow to olive-brown, with darker weathered bark and strong oxidation; sapwood is paler. Light exposure typically deepens the brown tone.
Hardness (Janka)
About 1,700 lbf Janka—Hard
Durability & Decay Resistance
Very Durable; heartwood has strong resistance to decay and insects, especially outdoors.
Value & Age
Approximately $5–12 per board foot for sound, dry, usable lumber; irregular rounds are commonly worth less.
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 standing/tree material appears recently cut, likely weeks to a few months; bark weathering does not reliably date the wood.
Common Uses
Posts, outdoor structures, fence rails, flooring, furniture, turning, and firewood.
Geographic Origin
Native to the eastern and central United States; widely planted and naturalized elsewhere.
Workability
Hard and abrasive but machines well with sharp tools; interlocked or irregular grain can tear out. Gluing and fastening are generally satisfactory after proper drying.
Finish Recommendations
Dry thoroughly, seal end grain to reduce checking, then use penetrating oil or exterior-rated polyurethane; sanding may require sharp abrasives.
Notable Features
Very heavy, dense wood with yellow-brown heartwood and excellent outdoor longevity; rounds may contain checking and reaction wood.
