GEOLOGICAL SUEVEY OF THE TEERITOEIES. 107 30 feet and behold a fairy-like palace, adorned with more brilliant colors and decorations than any structure made by human hands. South of the Thud Geyser, as laid down on the chart, there is one large basin, 150 feet in diameter, with a crater within the rim 25 feet in di- ameter. From this inner orifice the entire mass of wa- ter is thrown up 30 to 60 feet, fall- ing back into it, in detached glob- ules, like silver. There is a rim around the inner crater 3 feet high. The vast column s of water as it S shoots up, spreads ^ out in falling back, ^ like a natural foun- ^ tain, so that it t- overilowsthe inner % rim for a radius of ^ 10 feet. (Fig. 38.) ^ A short distance w south of the Foun- 1 tain Geyser is one S of the most re- ^ markable mud- pots in the Fire- Hole Valley. (Fig. 39.) The diameter within the rim is 40 bj^ 60 feet, and forms a vast mor- tar-bed of the fin- est material. The surface is covered with large puffs, and as each one bursts the mud spirts upward sev- eral feet with a sui^pressed thud. The mud is an im- palpable, siliceous clay, fine enough, it would seem, for the manufacture of the choicest ware. The colors are of every shade, from the purest white to a bright, rich pink. The surface is covered.
