pring season with flowers in

The base of the Mountain up to an altitude of about 4,000 feet is
covered by a somber forest of evergreens composed of the white and
black pines; Douglas, Lovely and Noble firs; the white cedar; spruce,
and hemlock. There are found also several deciduous trees--large-leafed
maple, {p.130} white alder, cottonwood, quaking aspen, vine and
smooth-leafed maples, and several species of willows. Thus the silva
of the lower slopes is highly varied. The forest is often interrupted
by the glacial canyons, and, at intervals, by fire-swept areas.

Among these foothills and valleys, lies the region of the virgin
forest. This area is characterized by huge firs and cedars, all tall,
straight and graceful, without a limb for 75 to 100 feet. This is
probably the most valuable area of timber in the world, and it is one
of the grandest parts of the Park. A death-like silence generally
pervades this cool, dark region, where few kinds of animal life find a
congenial abode. Occasionally the stillness is disturbed by the
Douglas squirrel, busily gnawing off the fir cones for his winter's
supply, or by the gentle flutter of the coy wren, darting to and fro
among the old, fallen logs. The higher forms of vegetable life are
also restricted to a few odd varieties. The most common of these are
such saprophytes as _pterospora andromedea_, _allotropa virgata_, the
so-called barber's pole, and the Indian pipe. This curious, waxy white
plant is generally admired by all who see it, but it quickly
disappoints those admirers who gather it by turning black.
The mosses, liverworts, and lichens take possession of the trees and
cover them with a unique decoration. The licorice fern often gains a
foothold on the trees thus decorated, and grows luxuriantly, embedded
in the deep growth of these plants.
It is nearly impossible to get through this region without following a
road or trail. For the safety of its priceless forest, there are far
too few trails. In case of a forest fire it would be impossible to
reach some areas in time to combat it with any success. Many beautiful
regions in the lower parts of the Park are {p.131} wholly
inaccessible. These should be opened with proper roads and trails, not
only for their own safety, but also for the benefit of visitors.
