FIG. 55.—SUMMIT OF THE CASCADE RANGE, NEAR THE HEAD OF THE SKAGIT RIVER
The forests of fir and hemlock have gained a foothold nearly to the summit of the range. Upon the little benches and in the protected nooks the trees grow thriftily, and dense groves are found up to an elevation of nearly five thousand feet; but upon the more exposed and rocky slopes stunted trunks show the effect of a constant struggle with the rocks and winds. Upon other slopes, too high for the trees to grow, there are low shrubs and arctic mosses; but above all rise precipitous crags and peaks, utterly bare except for the glaciers nestling among them.
Under the shade of the upland forests the moss is damp and the wood wet, so that it is difficult to make a comfortable camp or to build a fire. But these discomforts are not worthy of consideration in view of the inspiration which one gains by the outlook from some commanding point upon the summit of the mountain range.
All about are jagged, splintered peaks. Upon every gentle slope there rests, within some alcove, a glistening mass of snow and ice. A score of these glaciers are in sight. They are supplied in winter by the drifting snows, and yield in summer, from their lower extremities, streams of ice-cold water. A multitude of streams raise a gentle murmur, broken occasionally by a dull roar as some glacier, in its slow descent, breaks upon the edge of a precipice and its fragments fall into the cañon below.
From a position upon the summit above the point where the Skagit trail crosses the mountains may be seen a little lake, on the surface of which remains some of last winter's ice not yet melted by the August sun. If the climate were a little colder, the basin would be occupied by a glacier instead of a lake. All about the lake there are steep, rocky slopes, more or less completely covered with low arctic plants and stunted, storm-beaten hemlocks. From among the trees at the foot of the lake rises the roof of a miner's log cabin, and a few hundred feet beyond a small, dark opening in the face of a cliff shows where the miner is running a tunnel in his search for gold.
Far below, and heading close under the sharp crest of the range, are densely wooded cañons. The fair weather is passing, and it is necessary to find the trail and descend. Clouds are sweeping across the ridges and peaks, and soon the whole summit will be covered by them.
From a point a little east of the summit the clouds present a grand sight at the gathering of a storm. Higher and higher they pile upon the ocean face of the mountains. At the bottom they are dark and threatening, but the thunder-heads above can be seen bathed in the bright sunlight. For a time the clouds hang upon the summit as if stopped by some invisible barrier; perhaps they are loath to pass into the drier air of the eastern slope. But finally they move on, and rain or snow soon envelops the whole landscape.
The trail descends rapidly for four thousand feet to Cascade River, a tributary of the Skagit. It is a steep and slippery way, and in many places it is not safe to ride the horses. The sub-arctic climate of the summit is left behind, and one is soon surrounded by dense and luxuriant vegetation. Such a change as this, in a short distance, shows how greatly elevation affects climate and plant growth.
Upon every hand there is the sound of rushing water. From the cliffs ribbon-like cascades are falling. The rivulets unite in one stream, which roars and tumbles down the cañon over logs and boulders. The trail crosses and recrosses the torrent until the water becomes too deep for fording, and then it leads one to a rude bridge made of two logs with split planks laid across them.
