About the authors
Forrest Hopson
Forrest’s career as an experienced geologist involves research on the effects of volcanic activity on water resources in the Mammoth Lakes area and tectonic block rotations in southeast California. The results of his work have been presented at professional geologic conferences and published in geologic journals. He has a B.A. in Earth Science from California State University, Northridge (1984) and an M.S. in Geology from California State University, Los Angeles (1996). He is a member of the Geological Society of America and the Geological Society of Nevada. He does consulting work for mining and mineral exploration companies.
Michael Clynne
Michael has worked for the U.S. Geological Survey for 40 years. His research interests and primary expertise are stratigraphy, mineral chemistry, geochemistry, and petrology of arc volcanic rocks and the origin and evolution of magmatic systems. The majority of his geologic experience is in the study of young volcanic rocks, primarily in the Cascade Range, at the Lassen Volcanic Center, and Mount St. Helens. In 2010 he completed a geologic map of Lassen Volcanic National Park and vicinity. His map, published at 1:50,000 scale includes 2000 km squared of young volcanic terrane. He served as an associate editor for Bulletin of Volcanology, performed outreach and consultation on geologic matters for the National Park Service, and continues to collaborate with university colleagues on Lassen and Mount St. Helens research topics. He holds degrees in Earth Science: BS from the University of California at Santa Cruz (1976), MA from California State University-San Jose (1983), and a PhD from University of California at Santa Cruz (1993).

Reviews
"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."
–David Rains Wallace

"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."
