f Yellowstone is the most up-to-date and comprehensive reference to the geysers of Yellowstone National Park, describing in detail each of the park's more than five hundred geysers. The text has been revised and geyser descriptions have been updated based on activity observed through summer 2023. Information about a number of significant new geyser developments, including the conclusions of several recent seismic and other geophysical studies, have been added.

Both a reference work and a fine introduction to the nature of geyser activity, this popular field guide includes detailed maps of each geyser basin, tables for easy reference, and a glossary of key terms. A comprehensive appendix discusses other geyser areas of the world, several of which are described here for the first time. The Geysers of Yellowstone will continue to serve geyser gazers as well as newcomers to geothermal phenomena for years to come.
