The Book of the National Parks

by Robert Sterling Yard

The great north side, for instance, with its mighty walls, its magnificently scenic glaciers, its lakes, canyons, and enormous areas of flowered and forested pleasure-grounds, is destined to wide development; it is a national park in itself. Already roads enter to camps at the foot of great glaciers. The west side, also, with its four spectacular glaciers which pass under the names of Mowich and Tahoma, attains sublimity; it remains also for future occupation.

Many of the minor phenomena, while common also to other areas of snow and ice, have fascination for the visitor. Snow-cups are always objects of interest and beauty. Instead of reducing a snow surface evenly, the warm sun sometimes melts it in patterned cups set close together like the squares of a checker-board. These deepen gradually till they suggest a gigantic honeycomb, whose cells are sometimes several feet deep. In one of these, one summer day in the Sierra, I saw a stumbling horse deposit his rider, a high official of one of our Western railroads; and there he sat helpless, hands and feet emerging from the top, until we recovered enough from laughter to help him out.

Pink snow always arouses lively interest. A microscopic plant, Protococcus nivalis, growing in occasional patches beneath the surface of old snow gradually emerges with a pink glow which sometimes covers acres. On the tongue its flavor suggests watermelon. No doubt many other microscopic plants thrive in the snow-fields and glaciers which remain invisible for lack of color. Insects also inhabit these glaciers. There are several Thysanura, which suggest the sand-fleas of our seashores, but are seldom noticed because of their small size. More noticeable are the Mesenchytræus, a slender brown worm, which attains the length of an inch. They may be seen in great numbers on the lower glaciers in the summer, but on warm days retreat well under the surface.

The extraordinary forest luxuriance at the base of Mount Rainier is due to moisture and climate. The same heavy snowfalls which feed the glaciers store up water-supplies for forest and meadow. The winters at the base of the mountain are mild.

The lower valleys are covered with a dense growth of fir, hemlock, and cedar. Pushing skyward in competition for the sunlight, trees attain great heights. Protected from winter's severity by the thickness of the growth, and from fire by the dampness of the soil, great age is assured, which means thick and heavy trunks. The Douglas fir, easily the most important timber-tree of western America, here reaches its two hundred feet in massive forests, while occasional individuals grow two hundred and fifty to two hundred and seventy feet with a diameter of eight feet. The bark at the base of these monsters is sometimes ten inches thick. The western hemlock also reaches equal heights in competition for the light, with diameters of five feet or more. Red cedar, white pines of several varieties, several firs, and a variety of hemlocks complete the list of conifers. Deciduous trees are few and not important. Broad-leaved maples, cottonwoods, and alders are the principal species.

Higher up the mountain-slopes the forests thin and lessen in size, while increasing in picturesqueness. The Douglas fir and other monsters of the lower levels disappear, their places taken by other species. At an altitude of four thousand feet the Englemann spruce and other mountain-trees begin to appear, not in the massed ranks of the lower levels, but in groves bordering the flowered opens.

The extreme limit of tree growth on Mount Rainier is about seven thousand feet of altitude, above which one finds only occasional distorted, wind-tortured mountain-hemlocks. There is no well-defined timber-line, as on other lofty mountains. Avalanches and snow-slides keep the upper levels swept and bare.

The wild-flower catalogue is too long to enumerate here. John Muir expresses the belief that no other subalpine floral gardens excel Rainier's in profusion and gorgeousness. The region differs little from other Pacific regions of similar altitude in variety of species; in luxuriance it is unsurpassed.
