Summary

Summary

Written for the general reader with an interest in geology, natural history, and the early explorations of the US, this book is also a valuable guide for visitors to Sequoia and Kings Canyon National Parks. It describes the arduous travels of the early explorers, including John C. Fremont and John Muir, and weaves the history of exploration together with modern geological information, showing the early naturalists contributions to geological thought. Over 200 illustrations include contemporary etchings and maps, modern photographs, and geological diagrams to help visitors understand the formation of the natural features, and all technical terms that may be unfamiliar to non-geologists are simply and succinctly defined. Maps showing the region's principal roads and trails define the mileage between all lookouts and points of interest, and a geological guide to the southern half of the John Muir wilderness trail is featured.


Author Notes

James G. Moore is Senior Research Geologist Emeritus with the U. S. Geological Survey in Menlo Park, California.

Choice Review

Moore (US Geological Survey, Menlo Park, CA) offers a specialized account of the history, exploration, and the geology of one region--and much more than that. The Sierra Nevada Range in the region of Kings Canyon National Park and Sequoia National Park is the focus of this well-constructed report by a highly qualified author. The detail, though useful to any academic, is quite approachable for anyone with an interest in the region, in mountains, or in geology. Chapters deal with history, exploration, and mapping, as well as a geologist's world of time, rocks, mineral deposits, glaciation, and structures. All concepts and words are carefully explained in the text. Other features include a glossary; a road and trail guide; and many photos, maps, and drawings. The only weakness is a lack of discussion of touchy subjects, such as environmental issues with mining, or access issues with the parks. In sum, the book reads well, supported by all the precision and accuracy one would expect from a high-quality report from the US Geological Survey, but with the depth found from an earlier time. This quality production belongs in every library with an interest in geology--relevant to all readers, from specialists to nonmajors in an introductory course. Highly recommended. J. W.
