MOUNT RAINIER NATIONAL PARK NATURE NOTES
Vol. XVI September - December - 1938 Nos. 3 & 4


NOBLE FIR.
(Abies nobilis)

As the common name implies this tree is, in many respects, the finest of the true firs in Mount Rainier National Park. While it may be found at lower elevations it is most common in the intermediate zone, between 3500 and 4800 feet, where it is one of the principal species.

Mature specimens of this tree are usually from 100 to 150 feet tall and from 2 - 3-1/2 feet in diameter although larger trees may occasionally be found. The bark is thin, a dark ash-grey in color, seamed and ridged, and broken up into numerous small plates of irregular size. The color of the inner bark is a reddish-brown. The foliage, while varying somewhat in shade, is generally a deep blue-green with a silvery tinge and it is this character that is one of the most striking features of this tree. Individual needles are from 3/4 - 1-1/2 inches long. Those upon the upper branches are plump to four sided in cross section, pointed, densely massed and curved upward so that they appear to be growing from the top of the branches. Needles on the lower branches are flat, not curved, and generally notched at the tip. As in the case of all true firs they leave round leaf scars upon the branches when they fall or are pulled from them. However, the handsome and very beautiful cones are the most distinctive feature of this tree. These are 4-6 inches in length and 2-3 inches in diameter, yellow-green in color at maturity and with numerous pointed bracts protruding from between the cone scales. These scales bend down along the sides of the cylindrical cone to give it a "shingled" appearance. The cone of the noble fir is easily the most distinctive and unique of the cones possessed by local conifers. They stand upright upon the branches and, upon maturity, disintegrate as is characteristic of all true firs. The wood is rather heavy, fine grained, light brown in color and of good quality. It is the longest lived of any of our native true firs, reaching an age of from 200-400 years.

It ranges along the Pacific Coast in Washington and Oregon.
