Douglas Fir
Pseudotsuga menziesii

AKA: Oregon Pine
Photo taken on: November 17, 2007
Location: Trail 409, GV, CO
Life Zones: Foothills to subalpine
Habitat: Moist, shady canyons, north-facing slopes

Can grow to 180ft. Bark on mature trees is dark gray and furrowed. This is not a true fir. The needles are flat and blunt, and not bundled like pines, the cones point downward, not upwards like true firs. New growth is blue.

Cones are very distinctive with three-pronged bracts sticking out between the scales making the tree easy to identify.
