Various theories have been advanced toaccount for geyser action, but all have finallybeen abandoned in favor of that of Bunsen. Heconsiders that the Yellowstone region is ofvolcanic origin and of comparatively recent date,though it may be millions of years old, for thatmatter. There are masses of heated rock nearthe surface and in these are numerous fissuresthrough which the waters of Yellowstone Lakefind their way. When the steam thus generatedbeneath the water rises to a sufficient pressureit ejects the column above it, following in denseclouds. The intervals vary according to thetime required to fill the tube and generate thesteam, and should depend much on the size andshape of the subterranean cavity. Where thecirculation of the water is unhindered, a simplehot spring or pool will result, and these are morenumerous than the spouting geysers. From the 18.
