The western white pine (fig. 8) is found from southern Alaska to

northern California. In the park it occurs occasionally up to 4,000

feet. It usually grows on level benches and gentle slopes associated

with Douglas fir, western hemlock, and noble and amabilis fir. It

reaches its best development at elevations of from 3,000 to 3,500 feet,

where it attains a height of 150 feet and a diameter of 40 inches. The

shaft is straight, cylindrical, and clear of limbs. It bears a small,

narrow crown of drooping branches. In open areas, where it is exposed to

sunlight, its mode of growth is wholly different. The trunk is short,

rapidly tapering, and bears wide-spreading branches nearly to the

ground. At high elevations the western white pine is very short and

stunted.
