Douglas Fir (likely)

Pseudotsuga menziesiiSoftwood (gymnosperm/conifer)

Douglas Fir (likely)

Grain Pattern

Coarse, straight grain with prominent earlywood/latewood contrast; visible rough-sawn texture with checking (vertical cracks) common in large timbers

Color Description

Currently obscured by a dark charcoal/black opaque stain; naturally light brown to reddish-brown heartwood with yellowish sapwood. Luster is low due to rough surface and finish

Hardness Rating

660 lbf (Soft)

Durability Rating

Moderately Durable; heartwood is resistant to decay but sapwood is susceptible; generally requires treatment for ground contact

Common Uses

Structural timber, heavy construction, exterior posts, decking, and porch supports

Geographic Origin

Native to Western North America (Pacific Northwest)

Market Value & Sustainability

Estimated Market Value

$3.00 - $6.00 per board foot for structural clear timber

Wood Age Estimate

Modern construction timber (0-5 years); showing recent seasoning checks and fresh surface stain

Sustainability Status

Least Concern (IUCN); widely available and sustainably managed in North America; FSC certified options common

Workability

Standard for softwoods; easy to cut and nail, but prone to splintering and tearout on rough-sawn faces; resin can gum up blades

Notable Features

Prominent vertical checking (cracking) as the timber dries; high strength-to-weight ratio; distinct resinous scent when cut

Finish Recommendations

Solid color oil-based or acrylic outdoor stain (as shown) to protect against UV and moisture; requires periodic reapplication for exterior maintenance

Identification Confidence

Medium-High; the large timber dimensions, prominent earlywood/latewood texture visible through the stain, and standard structural application are hallmark of Douglas Fir posts
