AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.
- Wood Age Estimate
- Freshly milled dimensional lumber, likely less than 1-2 years since harvest, showing active sawmill conveyor context and unweathered surface.
Common Uses
Structural lumber, framing, beams, glulam members, plywood, veneer, exterior millwork, and heavy timber construction.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains)
Workability
Generally works easily with machine and hand tools, though the pronounced contrast between soft earlywood and dense latewood can cause uneven sanding or tearing during cross-grain planing. Holds fasteners well.
Finish Recommendations
Accepts standard oil- or water-based exterior and interior finishes, polyurethane, or penetrating exterior sealers. A sanding sealer or pre-stain conditioner is recommended prior to staining to prevent blotchiness from uneven ring density.
Notable Features
Distinctive resinous, sweet pine-like aroma when freshly cut; prominent, sharply defined growth rings; presence of resin/pitch pockets.
