[Old Faithful]
In imagination, lift in a symmetrical cone two hundred and fifty thousand gallons of scalding, steaming water one hundred and fifty feet high and hold it there three minutes; jewel the grand fountain with a million diamonds; filter through it the hues of innumerable dancing rainbows; commingle in confusion every sound of splash and splutter—and you will have a faint idea of Old Faithful in action.
It is the immutable water-clock of the Yellowstone—the most perfect illustration of geyseric phenomena—the most famous and beautiful geyser in the whole world.
The note of the beginning of the play of the geyser is an angry growl down deep in its throat whence almost instantly the water, in rapid recurrent leaps, forms the stately fountain that plays for three minutes and then slowly sinks into the earth to await its time to rise again. Sometimes the winds unfold from its top an iridescent banner of spray; but more often the fountain form is a perfect cone.
