Norris Geyser is another of the almost miraculous features of the park. The basin of the geyser has been described as a weird, uncanny place, and the words seem well chosen. Of vegetation there is practically none, because the underground heat keeps the ground always warm, and steam breaks out into the atmosphere at several points. The general aspect is drear and desolate, gray and dull, and yet there is something about it beautiful as well as uncanny.

A geyser is always a source of wonder. The word is of Icelandic derivation, and signifies gushing. As applied to phenomena such as we are now describing, its applicability is good, for, from the mouth of the geysers, there rushes from time to time an immense mass of boiling water and steam, creating a disturbance of no ordinary character. It is assumed that the water hurled into the air to a great height while at boiling point, has risen to the surface through masses of lava, which are reminiscent of volcanic ages far beyond the memory of mankind. The mystery of geological formation is too great to be gone into in a work of this character, but the bare contemplation of geysers, such as are seen at Yellowstone Park, reminds one of the wonders deeply hidden in the bowels of the earth, unappreciated and unknown by and to 99 per cent. of the human race.

At the Norris Geyser basin the noise is extraordinary, and people who are superstitiously inclined are awed at the rumblings and grumblings which seem to issue from the bowels of the earth. Eruptions of hot water and steam at irregular intervals burst forth, and the very road which crosses the adjoining plain has been bleached to almost perfect whiteness by the vapors. The crust of ground is very thin all around here, and indiscriminate exploring is dangerous. To slip through the crust into the boiling water beneath would inevitably involve being scalded to death, and the man who allows the guide to show him where to tread exhibits the greater wisdom.

In direct contrast to this basin is the Elk Park. Yellowstone is celebrated among other things for being the home of an immense number of the most remarkable specimens of North American animals. The Government herd of buffalo in the park is of countless value, because it is really the only complete representation at the present time of the practically extinct species of flesh and hide producing animals which used to graze by the million on the prairie. The buffalo are comparatively tame. Most of them were born within the confines of the park, and seem to have realized that the existence of their kind in perpetuity is one of the greatest desires of the Government. There are a number of bears around as well, but they have lost their viciousness, and enjoy life very hugely under somewhat changed conditions. They seldom hurt any one, but prowl around the hotels at night, and by eating up the scraps and leavings solve the garbage problem in a satisfactory manner.

Deer, elk, antelope and mountain sheep climb the mountains, and very frequently find their way into Elk Park or Gibbon Meadow. This is an exceptionally desirable wintering ground, because it is surrounded by hills and mountains which keep off the worst of the winds, and there is, moreover, a perpetual spring of pure water. The meadow is probably the prettiest spot in the entire park. There is less of the awful and more of the picturesque than can be found elsewhere, and it is, in many respects, an oasis in a vast and somewhat dreary expanse of land.

Golden Gate is another of the exquisite spots every visitor to Yellowstone Park seeks and finds. To reach the Golden Gate one must be a great climber, for it is high up, and the road to it is built along the edge of a cliff, which, in places, seems to be absolutely perpendicular. The gate is, however, worth reaching, and one is not surprised to hear that as much as $14,000 were spent in cutting out a single mile of the road to it through the rock.

Leaving the Golden Gate, and continuing the tour of inspection, a valley of large dimensions is seen. The contrast between the rich green of almost faultless verdure, and the dreariness of the rocks left behind, is striking. It would seem as though nature had built up an immense barrier between the weird and the natural, so that the one could not affect the other. The Bible speaks of the intense comfort of the shade of a great rock in a dry and thirsty land. A sensation of equal, if not greater, relief is experienced in Yellowstone Park when one leaves the grand, death-like desolation around the Hot Springs, and encounters the exquisite beauty of shrub land and timber but a few paces away. The groves of trees are in themselves sources of great delight, and also of immense wealth. Fortunately, they will be preserved in perpetuity for the American people. The lumber king cannot get here. His ravages must be confined to other regions.

The valley into which the tourist has entered takes its name from the Swan Lake, a very delightful inland mountain scene. The lake is about two miles from Golden Gate. It is not a very large body of water, but its rippling surface extracts expressions of admiration from all who behold it. It has been described as a demure looking sheet of water, and there is something about the appearance of the lake which seems to justify the peculiar definition. The cañon forming the valley is like everything else in Yellowstone Park--a little out of the ordinary. On the one side there are lofty mountains, with eminences and peaks of various formation and height, while in the distance the great Electric Peak can be easily seen. We have already spoken of Yellowstone Park as being about 10,000 feet above the sea level. Electric Peak, well described as the sentinel of the park, is more than 11,000 feet high. Viewed from a distance, or along the line of the valley, it is calculated to excite both admiration and awe.

Willow Creek Park, or Willow Park, as it is sometimes called, lies due south. It takes its name from the immense growth of willow bushes which hide the ground from view, and monopolize the scenery and groundwork entirely. None of these bushes can claim the right to be called trees, as the average height is inconsiderable. But they make up in density what they lack in altitude. The peculiar green of the willow is the predominating color, without any variation of any kind. The idea conveyed to the mind is of a huge green carpet or rug, and when the wind blows freely across the valley, it divides up the bushes into little ridges or furrows, which add to the uniqueness of the scene. Springs of remarkably pure water, many of them possessed of medicinal power, abound in this neighborhood, and tourists slake an imaginary thirst with much interest at different ones of these.

The Obsidian Creek runs slowly through this valley. Obsidian Cliff is the next object of special interest which is witnessed. It is half a mile long and from 150 to 200 feet high. The southern end is formed of volcanic glass, or obsidian, as true a glass as any artificially produced. The roadway at its base is constructed across the talus, and is emphatically a glass road. Huge fragments of obsidian, black and shining, some of it streaked with white seams, line the road. Small pieces are also plentiful. This flow of glass came from a high plateau to the east-northeast. Numerous vent pits, or apparent craters, have been discovered on this plateau. Mr. J. P. Iddings, of the Unites States Geological Survey, who has made a special study of Obsidian Cliff, contributes to the survey report for 1885-86 a paper that has in it much that is of interest to the unscientific mind.
