“The Castle has a very large, castellated, siliceous cone; the Grand has none whatever, nor is there any resemblance in their eruptions. The Oblong and the Giantess each expel their contents from deep, pit-like reservoirs, but there the resemblance between them ends. The Bee Hive and Old Faithful each have cones, as entirely unlike as are their splendid columns of water and vapor. Some throw the water as straight in the air as a tree stands; others hurl it out at various angles, or even in arches. Some send it forth in a solid, steady, majestic column; others in an irregular, churn-like fashion.
“But there are other things than the geysers here. Emerald Pool, Sunset Lake, and Black Sand Pool are, with one possible exception, the most delicate, beautifully colored bowls of water to be found in the park. The word color acquires a new significance as one stands at the verge of these truly heavenly pools, shut in among mountains.
“The particular attraction at the Fountain Hotel has been the Fountain Geyser near the hotel. This geyser has a basin some thirty feet in diameter, connected with another of about the same size just north of it. Much of the time these basins are full of water, thus, apparently, forming a large double crater.
NORRIS GEYSER BASIN, YELLOWSTONE PARK.
“In 1899 a new geyser, called the New Fountain, broke out in the north basin, resulting in a decided curtailment of the old Fountain Geyser’s eruptions. The new geyser is not yet old enough so that its periodicity and peculiarities are fully known. Its eruptions, however, are more stupendous and much beyond those of any other geyser which the writer has seen. Excelsior Geyser at Midway Basin, the greatest geyser—when it plays—in the world, is closely approached by this new giant, in both the magnitude and the grandeur of the display.
“The geyser is rather spurty in character, and when in full operation plays from three orifices. In its general action it is not unlike the Fountain or the Great Fountain. It will boil furiously and throw the water quite regularly to a height of ten to fifteen feet. Then, becoming semi-quiescent for a few moments, it will again break loose, and simply hurl into the air, with almost inconceivable force, a solid body of water of immense bulk, to a height of fifteen to thirty feet. Then changing again it will send upward an enormous volume of water to a height of 100, 150, or even, in exceptional spurts, 200 feet.
“After a period of momentary quiescence, the geyser will often break out with a violent explosion, when the scalding flood, transformed into millions of white, beautiful beads of crystal and spray, is sent in all directions, to all heights, at all angles, from the three apertures. The water is all torn to pieces and is thrown out and comes down, in a perfect avalanche. The geyser then is a very leviathan at play. It throws out pieces of geyser formation, bits of trees, and geyser eggs, as they are called, small, white, rounded, polished stones.
When the eruption ends it comes abruptly, at once, not as the Great Fountain’s, with a series of dying, tremendous throbs as if its great heart were broken. The eruption ceases, the great body of water drops rapidly down into the central cistern and runs into it from the geyser knoll in pretty little cascades, until the surplus is thus carried away and the water level outside of the basin is lowered. Then it is all over.
