asked me, "Do you want to get inside?" I replied, "Yes," but not until I had been told that the geyser plays so regularly that entering it is not at all foolhardy.

I judged the mouth to be an excellent place for a steam bath, but it was too warm for comfort; yet scarcely less comfortable was it than my state of mind as I wondered whether I would get safely through between the shots.
Thermal heat is required to produce geysers, but other causes have been known to precipitate one. Many years ago a packhorse fell into a hole in Geyser Valley, and shortly thereafter an eruption shook and shattered that place—and behold! the Packhorse Mud Geyser was born. For several days it played; then it
