Grain Pattern

Coarse, ring-porous texture with prominent broad rays visible on end grain sections, straight to slightly irregular longitudinal split grain.

Color & Appearance

Extremely weathered and sun-bleached silver-gray exterior with darkened, oxidized, dirt-caked end grain; interior underlying wood ranges from light tan to medium brown.

Hardness (Janka)

1,360 lbf (Hard)

Durability & Decay Resistance

Durable (heartwood has high rot and decay resistance, though sapwood and exposed split edges show surface weathering and insect bore holes)

Value & Sustainability

Estimated Market Value
$5.00 - $10.00 per board foot (standard lumber); minimal commercial value as weathered firewood/fence material
Wood Age Estimate
Harvested log segment aged 2 to 5+ years outdoors (weathered log pile)
Sustainability Status
Least Concern (IUCN), widely available, sustainable forestry practices

Common Uses

Firewood, rustic fence posts, timber framing, outdoor agricultural structures, reclaimed rustic furniture

Geographic Origin

Eastern and Central North America

Workability

Fair to hard; dense and tough to split or saw with hand tools, high ring density, moderate dulling effect on blades

Finish Recommendations

For rough firewood/outdoor use, no finish required. If processed into reclaimed lumber: deep brushing/sanding followed by penetrating oil or clear polyurethane sealer.

Notable Features

High tannin content causing dark discoloration when exposed to moisture/iron, deep radial checking (cracks), visible insect exit holes, distinct thick bark layer
