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.
