Western North America, particularly the Pacific Northwest and Rocky Mountain regions
Workability
Generally easy to work with both hand and machine tools, though the sharp contrast between earlywood and latewood density can sometimes cause splintering or uneven planing if tools are not kept very sharp
Finish Recommendations
Takes stains, sealers, varnishes, and paints well; exterior applications benefit from UV-blocking penetrating oils or marine varnishes
Notable Features
Distinctive straight and tight growth rings, high strength-to-weight ratio, pleasant resinous scent when freshly cut, contains moderate natural resins
