Marc S. Hendrix | Geology Underfoot in Yellowstone

Published: July 13, 2011

Geology professor Marc Hendrix has assembled an authoritative and thorough look at what makes the country’s oldest national park such a popular destination for millions of visitors every year.

“The sights and sounds of Yellowstone are a direct result of the region’s rich geologic history and the powerful tectonic forces that continue to shape it,” he writes.

If casual tourists only knew that a mere two miles beneath their feet, molten magma existed, they might be somewhat hesitant to tread the boardwalks among the mud pots.

The book is generously illustrated with informative diagrams, cross-section drawings, maps and photographs. Explanations are geared toward the lay reader.

The author takes us on a journey back into the vastness of geologic time, or “deep time,” to explain the origins and eventual changes to the region that shape the contemporary landscape. Particularly helpful are photographs of locations where features of geologic interest can be easily viewed.

Hendrix talks about the inner workings of geysers and the effects of earthquakes, detailing the Hebgen Lake earthquake of 1959. A helpful glossary of terms and a list of sources for those seeking more information are found in the back of the book.

Hendrix received his doctorate in applied earth sciences from Stanford University. He currently lives in Missoula with his family, and teaches at The University of Montana.

His new book was published by Mountain Press Publishing Company in Missoula, and sells for $24, softcover.
