Learn how geysers work and what they are.

Geysers. What makes them work? Many who have seen a geyser in action know only that it spouts hot water into the air. Many others have never seen one. Chapter 1, Geysers of the World, delineates their distinguishing features, locates the geyser regions of the world, and places investigations by world travelers and scientists in historic perspective. One of the quickest ways to become acquainted with a geyser is to observe it. The descriptions of several well known geysers, some based on past observations by others, but frequently by me, do not neces sarily portray current behavior. They do, however, represent general features. Geysers exist as a result of a delicate and unique interplay among the heat, the water, and the rocks of the earth. In essence, heat and water must be available, transported, distributed, stored, and finally released. Chapter 2, The Geologic, Thermal, and Hydrologic State of the Earth, especially that close to its surface, sets the stage for Chapter 3, Fundamentals of Geyser Operation. The geyser is treated here as a simple system consisting of three major interacting elements: a source of water, a source of heat, and a reservoir for storing water. The discus sion centers around the actions occurring within idealized columnar and pool geysers, and more complex systems. Some of the more workable geyser theories are evaluated.

This new edition of The Geysers of Yellowstone is the most up-to-date and comprehensive reference to the geysers of Yellowstone National Park, describing in detail each of the more than five hundred geysers in the park. The entire text has been revised and geyser descriptions have been updated based on activity observed through early 2018. Information about a number of significant new geyser developments has been added, as well as recent knowledge about some of the world’s geyser fields outside Yellowstone. Both a reference work and a fine introduction to the nature of geyser activity, this popular field guide includes a glossary of key terms, a comprehensive appendix that discusses other geyser areas of the world, detailed maps of each geyser basin, and tables for easy reference. The Geysers of Yellowstone will continue to serve geyser gazers as well as newcomers to geothermal phenomena for years to come.

This revised popular field guide describes in detail each of the more than 500 geysers in Yellowstone National Park. With updated information and a new foreword by park archivist Lee Whittlesey, Geysers of Yellowstone is both a reference work and a fine introduction to the nature of geyser activity for the newcomer to geothermal phenomena. A glossary of key terms is provided, along with a comprehensive appendix that discusses other geyser areas of the world. Detailed maps accompany each geyser basin described, and tables are provided for easy reference.

A commonly held theory of the origin of epithermal ore deposits relates Au, Ag, Hg, As, Sb, Tl, and other "volatile" elements to "fossil" hot-spring systems that transported and deposited these metallic elements close to the ground surface existing at the time. In the early 1970's, an emission-spectrographic method using short-wavelength radiation (SWR) was developed for use in the analysis of these "volatile" elements. This method was applied to 125 samples of rock and hot-spring chemical precipitates from Yellowstone National Park and 43 samples from Steamboat Springs, Nev. The results of those analyses are presented here. Recently, other, more sensitive methods for the analyses of gold and volatile elements have been developed and (or) become less expensive, but these methods generally have not yet been applied to Yellowstone samples. -- First paragraph.

Based on the graduate course in Earthquake Hydrology at Berkeley University, this text introduces the basic materials, provides a comprehensive overview of the field to interested readers and beginning researchers, and acts as a convenient reference point.
