Likely Douglas-fir; other conifers are possible from this end-grain view.
Pseudotsuga menziesii (provisional) · Softwood (conifer)
AI-generated identification · may be incorrect- Type
- Softwood (conifer)
- Origin
- Native to western North America, especially the Pacific Northwest and coastal and interior western regions.
- Hardness
- Janka about 660 lbf; Soft.
- Durability
- Slightly durable: heartwood has limited decay resistance; sapwood is vulnerable to insects and rot, especially outdoors when untreated.

Grain Pattern
End grain shows prominent, fairly even annual rings and a small, irregular central knot; the log appears cross-cut. Face-grain figure cannot be assessed.
Color & Appearance
Weathered gray-brown outer wood with warmer tan-brown areas; fresh Douglas-fir is typically pale yellow-brown to reddish-brown. Surface oxidation and lighting may alter the apparent color.
Hardness (Janka)
Janka about 660 lbf; Soft.
Durability & Decay Resistance
Slightly durable: heartwood has limited decay resistance; sapwood is vulnerable to insects and rot, especially outdoors when untreated.
Value & Age
Roughly US$3–8 per board foot for common retail lumber; grade, drying, dimensions, and region strongly affect price.
AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Cannot reliably estimate from the photograph; visible weathering indicates exposure, not the tree’s age.
Common Uses
Framing, structural lumber, flooring, doors, furniture, veneer, and plywood.
Geographic Origin
Native to western North America, especially the Pacific Northwest and coastal and interior western regions.
Workability
Generally machines and glues well, but resin can build up on blades and knots may cause tearout. Pre-drill near edges to reduce splitting.
Finish Recommendations
Sand evenly and use a compatible sealer, oil, or clear varnish; resinous knots may need spot sealing before topcoats.
Notable Features
Distinctive growth rings and resinous aroma when freshly cut; strong for its weight and widely used as structural timber.
