This is an admirably lucid, comprehensive, and well-illustrated guide to one of North America’s most active volcanic areas.  It tells a surprising amount about how this planet works, all the way from geological basics to sophisticated tectonic theories.

This informative and well-illustrated work will surely become required reading for anyone interested in geology who visits Lassen Volcanic National Park. Although famous for Lassen Peak’s violent and well-documented volcanic eruptions between 1914 and 1917, the greater Lassen Volcanic National Park region possesses a world-class variety of geological phenomena, which are described and interpreted for the reader in this book. Following a brief introduction, the authors – one a professional geologist and teacher and the other a research geologist with the US Geological Survey who has studied the Lassen Peak volcanic area for more than two decades – expertly guide the reader through the tectonic, volcanic, hydrothermal, and glacial history of the area. Readers also have the opportunity to follow a wonderful road guide with mile markers that direct the reader to specific deposits that geologists continue to use in their quest to better understand the geologic history of this dynamic and fascinating place.
