Douglas Fir
Pseudotsuga menziesii • Softwood
Grain Pattern
Generally straight and plain grain. Features high contrast between earlywood and latewood, creating a distinct ribbed texture in weathered samples. Flatsawn sections often show cathedral patterns, while this vertical/rift-sawn section shows tight, parallel lines.
Color Description
Heartwood is typically light brown with a hint of red or yellow. Sapwood is a lighter cream color. In this weathered state, it has developed a silvery-gray patina with remnants of golden-brown oxidation typical of sun-exposed conifers.
Hardness Rating
660 lbf (Soft)
Durability Rating
Moderately Durable; offers some resistance to decay but is susceptible to insect attack. Excellent strength-to-weight ratio for a softwood species.
Common Uses
Structural framing, heavy timbers, flooring, plywood veneer, joinery, and boat building. Often used in reclaimed beams and rustic furniture.
Geographic Origin
Western North America (Pacific Northwest, Rocky Mountains)
Market Value & Sustainability
Estimated Market Value
$4.00 - $9.00 per board foot depending on grade and whether it is reclaimed/clear vertical grain (CVG).
Wood Age Estimate
Reclaimed/Vintage; the deep grain erosion, graying patina, and surface checking suggest exposure to elements for 20-50+ years.
Sustainability Status
Not listed on CITES or IUCN Red List. Widely available as FSC certified and considered a sustainable, fast-growing timber resource.
Workability
Generally easy to work with machines, though it can be prone to splintering and breakout. It has a high resin content which can clog sandpaper and dull blades. Glues and finishes well but may require a sealer to prevent uneven staining.
Notable Features
Distinctive resinous, sweet odor when cut. High strength-to-weight ratio. The latewood is significantly harder than the earlywood, resulting in the distinct 'ridged' texture visible in this weathered sample.
Finish Recommendations
Penetrating oils or spar varnishes for outdoor use. Interior samples benefit from clear polyurethane or lacquer. Sanding with a hard block is necessary to prevent the softer earlywood from being scooped out.
Identification Confidence
High; the wide, dark latewood bands and tight vertical grain structure, combined with the specific way the wood has weathered and splintered, are classic markers of Douglas Fir.
