It will be readily seen from this description that the mountains which feed the Columbian system of rivers on the east and north, are of singular grandeur and interest. But now as we bear our way southward again we discover that another mountain system, yet grander and of more curious interest, forms the western boundary of the upper Columbia Basin. This is the Cascade Range. Sublime, majestic, mysterious, this noble chain of mountains, with its tiaras of ice, its girdles of waterfalls, its draperies of forest, its jewels of lakes, must make one search long to find its parallel in any land for all the general features of mountain charm. But over and beyond those more usual delights of the mountains, the Cascade Range has a unique feature, one in which it stands unrivalled among all the mountains of the earth, with the exception possibly of the Andes. This is the feature of the great isolated snow peaks, stationed like sentinels at intervals of from thirty to sixty miles all the way from the British line to California. There is nothing like this elsewhere on the North American continent. The Sierras of California are sublime, but their great peaks are not isolated monarchs like those of the Cascades. The high Sierras are blended together in one mountain wall, in which no single peak dominates any wide extended space. But in the long array of the Cascades, five hundred miles and more from the international boundary to the California line, one glorious peak after another uplifts the banner and sets its regal crown toward sunrise or sunset, king of earth and air to the border where the shadow of the next mountain monarch mingles with its own. Hence these great Cascade peaks have an individuality which gives them a kind of living personality in the life of any one who has lived for any length of time within sight of them.
