AI-generated identification · may be incorrect
Type
Softwood

Grain Pattern

Coarse, predominantly straight grain, obscured by deep checks, splintering, and weathering; no clear decorative figure or reliable evidence of sawing orientation.

Color & Appearance

The exposed surface is silver-gray to brown from weathering; fresh heartwood is typically reddish-brown, with paler sapwood. Sun and weather bleach and darken the surface unevenly.

Hardness (Janka)

About 350 lbf — Very Soft.

Durability & Decay Resistance

Durable heartwood; naturally resists decay and insects better than sapwood, but prolonged exposure has caused substantial surface checking and erosion.

Value & Age

Estimated Market ValueNot an official valuation

Roughly US$5–12 per board foot for ordinary clear or common stock; this severely weathered piece has little value as usable lumber.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Not reliably estimable from the image; heavy checking indicates prolonged outdoor exposure, not a specific age.

Common Uses

Exterior siding, shingles, decking, fencing, outdoor furniture, and boat components.

Geographic Origin

Western North America, especially coastal British Columbia and the Pacific Northwest.

Workability

Very soft and easy to cut and shape, but splinters and checks complicate machining; use sharp tools and predrill fasteners near edges.

Finish Recommendations

For a restored surface, remove loose fibers, allow it to dry, then use an exterior penetrating stain or suitable clear exterior finish; test first because weathering causes uneven absorption.

Notable Features

Lightweight, aromatic when freshly cut, and naturally decay-resistant; the pictured surface is deeply weathered and fractured.
