Even in these days of enlightenment and appreciation the great majority of people think of the Yellowstone only as an area enclosing geysers. There are tourists so possessed with this idea that they barely glance at the canyon in passing. I have heard tourists refuse to walk to Inspiration Point because they had already looked over the rim at a convenient and unimpressive place. Imagine coming two thousand miles to balk at two miles and a half to the only spectacle of its kind in the world and one of the world's great spectacles at that! As for the animals, few indeed see any but the occasional bears that feed at the hotel dumps in the evening.
The Yellowstone National Park lies in the recesses of the Rocky Mountains in northwestern Wyoming. It slightly overlaps Montana on the north and northwest, and Idaho on the southwest. It is rectangular, with an entrance about the middle of each side. It is the largest of the national parks, enclosing 3,348 square miles. It occupies a high plain girt with mountains. The Absarokas bound it on the east, their crest invading the park at Mount Chittenden. The Gallatin Range pushes into the northwestern corner from the north. The continental divide crosses the southwestern corner over the lofty Madison Plateau and the ridge south of Yellowstone Lake. Altitudes are generally high. The plains range from six to eight thousand feet; the mountains rise occasionally to ten thousand feet. South of the park the Pitchstone Plateau merges into the foothills of the Teton Mountains, which, thirty miles south of the southern boundary, rise precipitously seven thousand feet above the general level of the country.
Though occupying the heart of the Rocky Mountains, the region is not of them. In no sense is it typical. The Rockies are essentially granite which was forced molten from the depths when, at the creation of this vast central mountain system, lateral pressures lifted the earth's skin high above sea-level, folded it, and finally eroded it along the crest of the folds. In this granite system the Yellowstone is a volcanic interlude, and of much later date. It belongs in a general way to the impulse of volcanic agitation which lighted vast beacons over three hundred thousand square miles of our northwest. The Cascade Mountains belong in this grouping. Four national parks of to-day were then in the making, Mount Rainier in Washington, Crater Lake in Oregon, Lassen Volcanic in California, and the Yellowstone in Wyoming. Subterranean heat, remaining from those days of volcanic activity, to-day boils the water which the geysers hurl in air.
In the northeastern part of the Yellowstone a large central crater was surrounded by smaller volcanoes. You can easily trace the conformation from Mount Washburn which stood upon its southeastern rim, heaped there, doubtless, by some explosion of more than common violence. This volcanic period was of long duration, perhaps hundreds of thousands of years. In the northeastern part of the park the erosion of a hill has exposed the petrified remains of thirteen large forests in layers one on top of the other, the deep intervening spaces filled with thick deposits of ashes. Thirteen consecutive times were great forests here smothered in the products of eruption. Thirteen times did years enough elapse between eruptions for soil to make and forests to grow again, each perhaps of many generations of great trees.
Yellowstone's mountains, then, are decayed volcanoes, its rock is lava, its soil is ash and disintegrated lava. The resulting outline is soft and waving, with a tendency to levels. There are no pinnacled heights, no stratified, minareted walls, no precipiced cirques and glacier-shrouded peaks. Yet glaciers visited the region. The large granite boulder brought from afar and left near the west rim of the Grand Canyon with thousands of feet of rhyolite and other products of volcanism beneath it is alone sufficient proof of that.
Between the periods from volcano to glacier and from glacier to to-day, stream erosion has performed its miracles. The volcanoes have been rounded and flattened, the plateaus have been built up and levelled, and the canyons of the Yellowstone, Gibbon, and Madison Rivers have been dug. Vigorous as its landscape still remains, it has thus become the natural playground for a multitude of people unaccustomed to the rigors of a powerfully accented mountain country.
The fact is that, in spite of its poverty of peaks and precipices, the Yellowstone country is one of the most varied and beautiful wildernesses in the world. Among national parks it gains rather than loses by its difference. While easily penetrated, it is wild in the extreme, hinting of the prairies in its broad opens, pasture for thousands of wild ruminants, and of the loftier mountains in its distant ranges, its isolated peaks and its groups of rugged, rolling summits. In the number, magnitude, and variety of its waters it stands quite alone. It contains no less than three watersheds of importance, those of the Yellowstone, Madison, and Snake Rivers, flowing respectively north, west, and south. The waters of the Yellowstone and Madison make it an important source of the Missouri. There are minor rivers of importance in the park and innumerable lesser streams. It is a network of waterways. Its waterfalls are many, and two of them are large and important. Its lakes are many, and several are large. Yellowstone Lake is the largest of its altitude in the world.
As a wilderness, therefore, the Yellowstone is unequalled. Its innumerable waters insure the luxuriance of its growths. Its forested parts are densely forested; its flower-gardens are unexcelled in range, color, and variety, and its meadows grow deep in many kinds of rich grass. If it were only for the splendor of its wilderness, it still would be worth the while. Imagine this wilderness heavily populated with friendly wild animals, sprinkled with geysers, hot springs, mud volcanoes, painted terraces and petrified groves, sensational with breath-taking canyons and waterfalls, penetrable over hundreds of miles of well built road and several times the mileage of trails, and comfortable because of its large hotels and public camps located conveniently for its enjoyment, and you have a pleasure-ground of extraordinary quality. Remember that one may camp out almost anywhere, and that all waters are trout waters. Yellowstone offers the best fishing easily accessible in the continent.
Another advantage possessed by the Yellowstone is a position near the centre of the country among great railroad systems. The Northern Pacific reaches it on the north, the Burlington on the east, and the Union Pacific on the west. One can take it coming or going between oceans; it is possible to buy tickets in by any one railroad and out by either of the others. An elaborate system of automobile-coaches swings the passenger where he pleases, meeting all incoming trains and delivering at all outgoing trains. It is much easier now to see the Yellowstone than in the much-vaunted stage-coach times previous to 1915, times sorely lamented by the romantic because their passing meant the passing of the picturesque old horse-drawn stage-coach from its last stand in the United States; times when a tour of the Yellowstone meant six and a half days of slow, dusty travel, starting early and arriving late, with a few minutes or hours at each "sight" for the soiled and exhausted traveller to gape in ignorant wonder, watch in hand.
To-day one travels swiftly and comfortably in entire leisure, stopping at hotels or camps as he pleases, and staying at each as long as he likes. The runs between the lingering places are now a pleasure. If hurried, one can now accomplish the stage-coach trip of the past in two days, while the old six and a half days now means a leisurely and delightful visit.
