ОглавлениеThe Yellowstone National Park, Wyoming Mammoth Hot Springs. Summit Pools LINK TO IMAGE
Opposite the base of Obsidian Cliff is Beaver Lake, the home of numerous beavers and a great resort for waterfowl during a part of the year. After passing Obsidian Cliff, hot springs become more numerous until we reach Norris Geyser Basin. In this locality the odor of sulphur is strong and unpleasant. A little farther on a loud roar startles us, and a few moments later we see the cause of the explosion; it is a powerful steam jet issuing from the summit of Roaring Mountain. When Dame Nature "turns on steam" there is no nonsense about it.
Norris Basin seems to be of more recent volcanic development, since some of the steam vents in other basins have ceased action during the past few years; moreover, several new ones have opened, one of which rivals Roaring Mountain. Constant and Minute-Man Geysers, though small, are frequent and vigorous in action. In passing through this section the road-bed is hot for some distance, showing that the subterranean rocks which heat the water cannot be very deep down in the earth.
In going to the Firehole Basins we follow Gibbon River to within four miles of its mouth, then, crossing a point of land to the Firehole, we ascend the right bank of the stream to Lower Basin. On the road we pass many springs; the most conspicuous of which, Beryl Spring, lies close to the road. It discharges a large volume of boiling water and the rising steam frequently obscures the road.
In one locality outside the beaten track of tourists there is a veritable Hades on earth. Here, as we walk over ground that is very hot, we are nearly suffocated by the fumes of sulphur. All around us are hundreds of seething, boiling vats of water, and the whole area is cracked and filled with holes from which noxious vapors rise.
Soon after we leave this infernal region we hear a constant roar like that coming from a large steamer about to leave its moorings. We follow in the direction from which the sound proceeds and at length discover the cause.
On approaching the source of the sound we see a large volume of steam rushing with immense velocity from an opening in the ground, while the rock around the orifice is black as jet. The guide tells us that this huge steam vent is called the Black Growler, and that it continues vigorously active summer and winter, year in and year out. Its roar can be heard four miles away.

The chief wonder of Lower Firehole Basin is the Great Fountain Geyser. Its formation is unique. At first sight one is led to believe that the broad circular structure which he sees is artificial. On close inspection numerous pools, moulded and nicely ornamented, are seen sunk in this stone table, while in the centre there is a large and deep pool filled with hot water, but looking like a beautiful spring. At the time of eruption this central pool of water is shot up to the height of one hundred feet or more. Near the Great Fountain Geyser is a small valley in the upper part of which is a large hot spring called the Firehole.
When this spring is visited on a windless day, a light-colored flame seems to be constantly issuing from the bottom, flickering back and forth like a torch, and the visitor feels sure he is gazing at the hidden fires beneath that heat the water. It is the illusion caused by superheated steam escaping through a fissure in the rock and dividing the water. The reflection from the surface thus formed and a black background formed by the sides and bottom of the pool account for the phenomenon.
Surprise Pool is found near the Great Fountain; it will make good its name should you throw into it a handful of dirt. Excelsior Geyser, not far away, is really a winter volcano, its crater being a seething caldron near the Firehole River, into which it sends six million gallons of water each day, even when not in eruption.
At times it sends up a column of water, fifty feet in diameter, to the height of two hundred and fifty feet. The eruptions take place at long intervals—seven to ten years. On account of the great depth and extent of this geyser it has sometimes been denominated "Hell's Half-Acre."
Following along Firehole River we pass into the Upper Basin, a section the most popular with the majority of tourists. Among the geysers in this basin we shall find Grotto, Castle, Giant, Giantess, Bee Hive, Splendid, Grand, and Old Faithful. Each of them has an interest peculiarly its own, but Old Faithful is always true to its name and is perhaps best appreciated by visitors.
The opening through which Old Faithful disgorges its water is at the summit of a mound built up by its own exertions. The wrinkles on its face tell of long-continued service. Every seventy minutes this faithful worker sends up a column of water to the height of one hundred and eighty feet, and at each eruption more than one million gallons of water are thrown out.
We now pass through a section noted for its wild and picturesque scenery and considered the pleasantest on the trip. In leaving the Upper Basin we follow along Firehole River to the mouth of Spring Creek, then along this creek to the Continental Divide. From there, travelling a few miles along the Pacific slope, we cross the Divide and descend the mountains into the valley of the Yellowstone.
Near the central part of the park, encircled by a forest and elevated nearly eight thousand feet above the sea-level, lies a remarkable body of water supplied by ice-cold streams formed by the melting snow on the surrounding mountains. This body of water, of which the Yellowstone River is the outlet, is the famous Yellowstone Lake, thirty miles long and twenty miles wide; it is filled with trout.
Here the fisherman can catch hundreds of trout in a short time, but unfortunately most of them are afflicted with a parasitic disease, rendering them unfit for food. Researches have been made seeking the cause of the disease in order, if possible, to apply a remedy, but so far to no purpose. It is conjectured that the superabundance of fish together with a dearth of suitable food lowers their vitality, thus rendering them liable to disease.
Yellowstone stands next to Lake Titicaca as the highest large body of water in the world. The sunrise and sunset effects on the lake are most beautiful. A steamer plies on the lake carrying mail and passengers. The bird life on this body of water and its shores is represented by swans, geese, ducks, cranes, pelicans, curlews, herons, plovers, and snipe.
For beauty and grandeur the lower falls and canyon of the Yellowstone River are unsurpassed. A body of water seventy feet wide rushes forward with impetuous speed and joyously takes a leap of more than three hundred feet to the rocks below, where, breaking into millions of particles, it forms a great cloud of spray. The water then dashes on with renewed vitality between the walls of a canyon fourteen hundred feet deep, and most gorgeously painted by nature in such a variety and lavishness of tints that they defy the most skilful artist to reproduce them.
As one gazes from the edge of the chasm into and along the depths below, he attempts in vain to measure the fulness and beauty of this handiwork of nature. He is too amazed for utterance and remains spellbound, communing only with himself and nature regarding the unfathomable significance of such marvels. When the famous painter, Thomas Moran, desired to reproduce in colors on canvas this masterpiece of nature, he gathered his inspiration from Artist Point, and after he had finished the celebrated painting which now adorns the Capitol at Washington, he acknowledged that the beautiful tints of the canyon were beyond the reach of human art.
The Grand Canyon of the Yellowstone has no equal on the face of the globe. With a breadth equal to its depth, this richly decorated canyon stands out unique among the world's wonders. Its beautiful panorama of stained walls, down which trickle streams of water which brighten the tints in some places and soften them in others, extends for a distance of three miles. The entire canyon is fifteen miles in length.
A most interesting place to visit, but outside the itinerary of most tourists, is the Fossil, or Petrified, Forest. This section, especially attractive to the scientist, lies in the northeastern part of the park just north of Amethyst Mountain.
To one who can read Nature's books, a wondrous volume is open, disclosing in its strata the hidden secrets of many by-gone geological ages. Here on the north flank of the mountain are two thousand feet of stratifications. On the ledges, tier above tier and story above story, are seen the opal and agate stumps and trunks of twenty ancient forests, some of the trunks being ten feet in diameter.
What wonderful stories do they tell of life and death, of flood and volcanic fire, ranging through the eons of the past! So perfect are these petrifactions that the annual rings can be easily counted and even the grain of the wood is plainly visible.
As one traverses this wonderland he is impressed by the evidence of the stupendous forces that lie smouldering beneath the crust of the earth. It is not improbable that at some future time, by the further wrinkling or sinking of the surface of this part of the American continent, the slumbering volcanic fires may be awakened to new life and activity.
