While these gracious rains are searching the roots of the lowlands, corresponding snows are busy along the heights of the Cascade Mountains. Month after month, day and night the heavens shed their icy bloom in stormy, measureless abundance, filling the grand upper fountains of the rivers to last through the summer. Awful then is the silence that presses down over the mountain forests. All the smaller streams vanish from sight, hushed and obliterated. Young groves of spruce and pine are bowed down as by a gentle hand and put to rest, not again to see the light or move leaf or limb until the grand awakening of the springtime, while the larger animals and most of the birds seek food and shelter in the foothills on the borders of the valleys and plains.
The lofty volcanic peaks are yet more heavily snow-laden. To their upper zones no summer comes. They are white always. From the steep slopes of the summit the new-fallen snow, while yet dry and loose, descends in magnificent avalanches to feed the glaciers, making meanwhile the most glorious manifestations of power. Happy is the man who may get near them to see and hear. In some sheltered camp nest on the edge of the timberline one may lie snug and warm, but after the long shuffle on snowshoes we may have to wait more than a month ere the heavens open and the grand show is unveiled. In the mean time, bread may be scarce, unless with careful forecast a sufficient supply has been provided and securely placed during the summer. Nevertheless, to be thus deeply snowbound high in the sky is not without generous compensation for all the cost. And when we at length go down the long white slopes to the levels of civilization, the pains vanish like snow in sunshine, while the noble and exalting pleasures we have gained remain with us to enrich our lives forever.
The fate of the high-flying mountain snow-flowers is a fascinating study, though little may we see of their works and ways while their storms go on. The glinting, swirling swarms fairly thicken the blast, and all the air, as well as the rocks and trees, is as one smothering mass of bloom, through the midst of which at close intervals come the low, intense thunder-tones of the avalanches as they speed on their way to fill the vast fountain hollows. Here they seem at last to have found rest. But this rest is only apparent. Gradually the loose crystals by the pressure of their own weight are welded together into clear ice, and, as glaciers, march steadily, silently on, with invisible motion, in broad, deep currents, grinding their way with irresistible energy to the warmer lowlands, where they vanish in glad, rejoicing streams.
In the sober weather of Oregon lightning makes but little show. Those magnificent thunderstorms that so frequently adorn and glorify the sky of the Mississippi Valley are wanting here. Dull thunder and lightning may occasionally be seen and heard, but the imposing grandeur of great storms marching over the landscape with streaming banners and a network of fire is almost wholly unknown.
