Elsewhere throughout the park the innumerable hot springs seem to be less charged with depositable matter; elsewhere they build no terraces, but bubble joyously up through bowls often many feet in depth and diameter. Often they are inspiringly beautiful. The blue Morning Glory Spring is jewel-like rather than flower-like in its color quality, but its bowl remarkably resembles the flower which gives it name. Most springs are gloriously green. Some are the sources of considerable streams. Some stir slightly with the feeling rather than the appearance of life; others are perpetually agitated, several small springs betraying their relationship to the geysers by a periodicity of activity. When the air is dry and the temperature low, the springs shoot thick volumes of steam high in air. To the incomer by the north or west entrance who has yet to see a geyser, the first view of the Lower Geyser Basin brings a shock of astonishment no matter what his expectation. Let us hope it is a cool, bracing, breezy morning when the broad yellow plain emits hundreds of columns of heavy steam to unite in a wind-tossed cloud overlying and setting off the uncanny spectacle. Several geysers spout vehemently and one or more roaring vents bellow like angry bulls in a nightmare. This is appropriately the introduction to the greater geyser basins which lie near by upon the south. Who shall describe the geysers? What pen, what brush, shall do justice to their ghostly glory, the eager vehemence of their assaults upon the sky, their joyful gush and roar, their insistence upon conscious personality and power, the white majesty of their fluted columns at the instant of fullest expansion, the supreme loveliness of their feathery florescence at the level of poise between rise and fall, their graciousness of form, their speedy airiness of action, their giant convolutions of sun-flecked steam rolling aloft in ever-expanding volume to rejoin the parent cloud? Perhaps there have been greater geyser basins somewhere in the prehistoric past. There may be greater still to come; one or two promising possibilities are in Alaska. But for the lapse of geologic time in which man has so far lived, Yellowstone has cornered the world's geyser market. There are only two other places where one may enjoy the spectacle of large geysers. One of these is New Zealand and the other Iceland; but both displays combined cannot equal Yellowstone's either in the number or the size of the geysers.
