Ponderosa Pine
Pinus ponderosa • Softwood
Grain Pattern
Straight, coarse grain with visible growth rings; transition between earlywood and latewood is somewhat abrupt. Likely flat-sawn with rough-sawn texture visible.
Color Description
Heartwood is reddish-brown, sapwood is yellowish-white. The sample shows significant oxidation and graying due to unfinished exposure, with a dull luster and blue-gray fungal staining.
Hardness Rating
460 lbf (Very Soft)
Durability Rating
Slightly Durable to Non-durable. Susceptible to rot and insect attack if left untreated in moist conditions.
Common Uses
Construction lumber, utility shelving, crates, boxes, and residential framing.
Geographic Origin
Western North America (Pacific Northwest and Rocky Mountains)
Market Value & Sustainability
Estimated Market Value
$1.50 - $3.00 per board foot for utility grade
Wood Age Estimate
30-50 years based on surface oxidation, secondary patina, and the presence of aged blue-stain fungi.
Sustainability Status
Least Concern (IUCN); widely available and not CITES listed.
Workability
Easy to work with hand and machine tools. Softness makes it prone to indentations and fuzzy surfaces if tools are dull. Glues and finishes well but can be resinous.
Notable Features
Distinctive resinous scent when cut; presence of blue stain (sapstain) which does not affect structural integrity but impacts aesthetics.
Finish Recommendations
Penetrating oil or film-building polyurethane after thorough sanding to remove oxidized fibers and staining.
Identification Confidence
Medium; the coarse grain, soft texture, and characteristic blue-staining are highly indicative of a Western Softwood like Ponderosa Pine or Lodgepole Pine.
