To attempt any thing like a detailed description of the Firehole Geyser regions would be intolerable alike to reader and author. Of the objects of interest, any one of which in other localities would attract marked attention, there are several thousand. In the present description, therefore, only the more important features will be noticed--those notable objects to see which is an indispensable part of any well ordered tour of the Park. The _Fountain Geyser_ is a typical example of the first class of geysers described in a previous chapter. Its proximity to the hotel (one-fourth mile) causes it to be much visited. _The Mammoth Paint Pots_, a little way east of the Fountain, are probably the most prominent example of this class of phenomena in the Park. The _Great Fountain Geyser_ lies a mile and a half south-east of the Fountain. It is the chief wonder of the Lower Basin, and, in some respects, the most remarkable geyser in the Park. Its formation is quite unlike that of any other. At first sight the visitor is tempted to believe that some one has here placed a vast pedestal upon which to erect a monument. It is a broad, circular table about two feet high, composed entirely of hard siliceous deposit. In its surface are numerous pools molded and ornamented in a manner quite unapproached, at least on so large a scale, in any other part of the Park. In the center of the pedestal, where the monument ought to stand, is a large irregular pool of great depth, full of hot water, forming, to all appearances, a lovely quiescent spring. At times of eruption, the contents of this spring are hurled bodily upward to a height sometimes reaching 100 feet. The torrent of water which follows the prodigious down-pouring upon the face of the pedestal, flows away in all directions over the white geyserite plain. No visitor to the Yellowstone can afford to miss the Great Fountain Geyser. In this vicinity are several of the handsomest springs in the Park. One in particular lies just across the hot stream which flows a little to the south of the Great Fountain. It is shaped like an egg set endwise in the ground with the upper part of the shell broken off. It is an exquisite trifle. In a small valley, extending to the north-east from the Great Fountain, are several objects worthy of notice. One of these is an immense hot lake, by far the largest in the Park. _Steady Geyser_ and _Young Hopeful_, near the head of the valley, are not remarkable in this land of geysers.
