Grain Pattern
Straight to irregular growth rings following log curvature, uneven growth ring spacing due to harsh mountain environment
Color & Appearance
Exposed end-grain is weathered silver-gray with darker oxidation; the exposed split section shows rich reddish-amber to golden-brown resinous heartwood (fatwood) with cream-colored sapwood near the outer bark
Hardness (Janka)
460 lbf (Soft)
Durability & Decay Resistance
Moderately Durable to Durable when heavily saturated with natural pine resin; otherwise slightly durable and susceptible to decay
Value & Sustainability
- Estimated Market Value
- $2.00 - $4.00 per board foot for standard lumber; sold as fatwood kindling by weight ($3 - $6 per lb)
- Wood Age Estimate
- Tree age approximately 40-80 years based on visible rings; cut stump weathered in the environment for 5-15+ years
- Sustainability Status
- Least Concern (IUCN); widely managed and abundant across western North American forests
Common Uses
Fire starter (fatwood kindling), rustic turning, carving, utility lumber, poles, and paper pulp
Geographic Origin
Western North America (Rocky Mountains, Cascade Range, Sierra Nevada)
Workability
Easy to cut and carve, but extremely gummy tools due to high resin/pitch content; clogs sandpaper and dulls saw blades quickly
Finish Recommendations
Requires solvent wiping (denatured alcohol or mineral spirits) to remove surface resin before applying film finishes like shellac or lacquer; best left natural or sealed with penetrating oil if cured
Notable Features
Strong pine resin odor, highly flammable due to terpene accumulation (fatwood), visible heartwood resin saturation, thick protective bark
