High; the unmistakable dark blue-gray staining pattern paired with softwood pine grain and fine growth ring structure strongly indicates beetle-stained ponderosa or lodgepole pine. confidence

Ponderosa Pine (Blue Stain Pine / Beetle Killed Pine)

Pinus ponderosa · Softwood

Type: Softwood
Origin: Western Coast and Rocky Mountain regions of North America.
Hardness: 460 lbf (Very Soft)
Durability: Non-durable to Slightly Durable; susceptible to rot and insect attack if untreated and exposed to moisture, though the blue stain fungus itself does not compromise structural integrity.

Grain Pattern

Straight, fine-to-medium texture with subtle cathedral growth ring patterns and small pinpoint knots.

Color & Appearance

Pale yellowish-tan natural wood tone prominently affected by blue-gray to denim-colored fungal staining (blue stain caused by Grosmannia clavigera, transmitted by mountain pine beetles).

Hardness (Janka)

460 lbf (Very Soft)

Durability & Decay Resistance

Non-durable to Slightly Durable; susceptible to rot and insect attack if untreated and exposed to moisture, though the blue stain fungus itself does not compromise structural integrity.

Value & Sustainability

Estimated Market Value: $3.50 - $6.50 per board foot depending on grade and intensity of blue stain figure.
Wood Age Estimate: Modern lumber, likely harvested within the last 5 to 15 years following pine beetle infestations.
Sustainability Status: Least Concern (IUCN); highly sustainable and environmentally beneficial as it utilizes salvaged timber from beetle-killed forests.

Common Uses

Rustic furniture, wall paneling, cabinetry, decorative crafts, picture frames, millwork, and accent walls.

Geographic Origin

Western Coast and Rocky Mountain regions of North America.

Workability

Very easy to work with both hand and machine tools. Glues, sands, and fastens exceptionally well, though soft earlywood can be prone to tearing if cutters are dull.

Finish Recommendations

Clear finishes such as film-building polyurethane, lacquer, or natural oils (danish or tung oil) to highlight the striking blue contrast without muddying the grain.
