What They Are and How They Work

T. Scott Bryan

In Geysers: What They Are and How They Work, T. Scott Bryan explains the geological setting that produces the pressure, heat, and abundant water necessary for a geyser to form and introduces readers to the variables that shape each geyser’s distinct personality. Some geysers spout just inches above a pool of water and others blast hundreds of feet in the air from conical vents. Some remain quiet for decades only to explode unexpectedly several times in a single month while others regularly erupt at scheduled intervals.
While Scott focuses on Yellowstone National Park, he also draws examples from geyser fields in Iceland, Chile, Russia, New Zealand, and elsewhere. An appendix with a detailed map describes the status of more than sixty geyser fields around the world.
