Geology of the Sierra Nevada

This is an excellent review of the complicated and interesting geology of California's Sierra Nevada. I particularly liked the section at the beginning of the book, a step-by-step process to identify different rocks. The steps are easy to understand and execute, even for a layman. Another useful feature of the book is the set of maps showing locations where one can find each different rock type. The book outlines geological processes (such as volcanism and plate tectonics) and features (e.g., fault lines), and explaines how the present Sierra Nevada was formed. One particularly useful feature of the volume is that its size and weight allows that a hiker or a climber or a backpacker can carry it with him or her.

Excellent read, very good field guide

Geology of the Sierra Nevada (California Natural History Guides) I enjoy science books that take a historical approach, explaining when and how the facts were determined. This approach brings science to life. Besides the historical information, this book is a comprehensive reference that I will carry with me on hikes in the Sierras.

Teachers reference

This is a nice reference source for general geologic information on Sierra Nevada. A definite improvement over the last edition, worth the replacement cost. Too bulky for a field guide unless you like spending your outing buried in a book, but is a great size for student use in class. The breadth of topics is excellent, and material is up to date (not all books available are). For anyone who needs exposure to Sierra Nevada geology, this is a good supplement to the Harden Book

They're not just rocks, they're history

Three decades ago geologist Mary Hill wrote a handbook to the Sierra Nevada's geologic history and it became the standard guide. The aptly named author has now extensively revised her book. It's an armchair traveler's delight and remains an authoritative guide that will well serve a new generation of hikers, campers, and explorers. "Geology of the Sierra Nevada: Revised Edition" ($19.95 in full-color paperback from University of California Press) contains almost 200 illustrations, including photographs of rock forms and maps showing where to find them. Hill thanks Bill Guyton, professor emeritus of geosciences at Chico State University, "for his careful reading" of the new manuscript and draws on the research he published in "Glaciers of California" (1998). Guyton distinguished between glaciers and smaller "glacierets" and counted 99 glaciers in the Sierra Nevada and 398 glacierets. Hill notes that "the Sierra Nevada has a lot of glaciers, all of them small. If you are looking for the giants of the Great Ice Age, you will have to be content with their spoor." The book is divided into two sections. The first offers a "do-it-yourself rock identification key." A series of maps divides the Sierra Nevada into regions and shows where to find prominent rock formations in each area. The first map, mostly of eastern Butte County, locates "conglomerate" ("rock ... made up of grains 2 mm or more in diameter, together with coarser fragments") along Big Chico Creek. You can see shale in the Dry Creek area and lava flow and basalt on Table Mountain. The second part is the narrative, which takes new research into account. In the last few years, she writes, "the Sierra has been put through the plate tectonics intellectual filter, which has told us how the mountains might have been created, and why they are where they are." The book also expands its coverage of "human exploration of the Sierra Nevada, not just by geologists" but by others as well. Here you'll find the story of "the first overland party of settlers to attempt to cross the Sierra. ... The group came to be known as the Bartleson-Bidwell party, as it included two men of leadership mold, John Bartleson and John Bidwell, destined to become eminent in what was to be the 31st U.S. state." Here also is the story of "Snowshoe" Thompson, a Norwegian who for two decades, "beginning in 1856, ... carried the mail across the Sierra Nevada from Placerville, California, to Genoa, Nevada (then called Mormon Station), using long skis (then called 'snowshoes') of his own making." But Hill's great love is the land itself, the "nervous" Sierra, and her account of the devastating Owens Valley earthquake in 1872 tells not only of human destruction but notes that "the Sierra Nevada itself was severely wracked." She quotes John Muir's eyewitness account: "Shortly after sunrise a low, blunt, muffled rumbling, like a distant thunder, was followed by another series of shocks, which ... made the cliffs and domes tremble
