Product Description

At various times in a span of fifteen years, John McPhee made geological field surveys in the company of Eldridge Moores, a tectonicist at the University of California at Davis. The result of these trips is Assembling California, a cross-section in human and geologic time, from Donner Pass in the Sierra Nevada through the golden foothills of the Mother Lode and across the Great Central Valley to the wine country of the Coast Ranges, the rock of San Francisco, and the San Andreas family of faults. The two disparate time scales occasionally intersect—in the gold disruptions of the nineteenth century no less than in the earthquakes of the twentieth—and always with relevance to a newly understood geologic history in which half a dozen large and separate pieces of country are seen to have drifted in from far and near to coalesce as California. McPhee and Moores also journeyed to remote mountains of Arizona and to Cyprus and northern Greece, where rock of the deep-ocean floor has been transported into continental settings, as it has in California. Global in scope and a delight to read, Assembling California is a sweeping narrative of maps in motion, of evolving and dissolving lands.

Amazon.com Review
As an explainer, John McPhee is a national treasure. The longtime "New Yorker" staff writer has taken us inside the world of art museums, environmental groups, fruit markets, airship factories, basketball courts, and atomic-bomb labs the world over. Here he covers the complex geological history of California, the source of much news today. As Californians daily await the inevitable great earthquake that will send their cities tumbling down like so many matchsticks, McPhee piles fact on luminous fact, wrestling raw data into a beautifully written narrative that gainsays a sedimentologist's warning: "You can't cope with this in an organized way," he told McPhee, "because the rocks aren't organized." As always, McPhee enlarges our understanding of the strange, making it familiar--and endlessly interesting.

From Publishers Weekly
In his usual clean, graceful prose, McPhee takes readers on an intensive geological tour of California, from the Sierra Nevada through wine country to the San Andreas fault system, a 50-mile-wide swath of parallel fault lines. Through talks with his traveling companion, geologist Eldridge Moores, McPhee introduces the reader to current geological controversies, and surveys global plate tectonics--the collision and rearrangement of land masses ever since the breakup of the supercontinent of Pangaea eons ago. The duo also travel to Arizona, where Moores grew up pushing ore carts in his family's gold mine, and to Cyprus and Greece, where rock from the ocean floor has been tossed up to form continents. McPhee looks at the conjectural science of earthquake prediction and gives an account of a recent San Francisco quake. His leisurely excavation meanders from Mexican explorer Juan Bautista de Anza's settlement of San Francisco in 1776 to 1850s gold-mining camps to the summit of Mount Everest, made of marine limestone lifted from a shelf that once divided India and Tibet. With this volume McPhee concludes his Annals of the Former World series, which he began with Basin and Range (1980). Illustrated.

From Library Journal
With this work McPhee completes his book series on regional geology in the United States. The author of more than 20 works on a wide range of topics ( Looking for a Ship , LJ 8/90; The Control of a Nature , LJ 4/1/89), he has a talent for relating complex concepts in a simple, interesting manner. McPhee spent portions of 15 years traveling world-wide with geologist Eldridge Moores in search of supporting evidence for the theory that California moved on shifting plates (continental drift) to become affixed to North America. He also discusses the history of mining in the state and offers sobering implications for those living near the San Andreas fault complex. Although portions of this book may be beyond the scope of the average reader, it should appeal to armchair scientists, rockhounds, and fans of McPhee's other works. Recommended for larger public as well as academic collections. Previewed in Prepub Alert, LJ 9/1/92.

A geologic road accident
If anyone tells you "science destroys beauty," respond by handing them a McPhee. Any of his works will suffice, but this one is a special treasure. It's the completion of a continent-wide tour across the United State. McPhee escorts a succession of geologists who have explained to him why the theory of continental drift requires revision. The modifiers are local geological conditions, each region telling its own tale of lithic activity. In California, the story becomes almost bizarre. John McPhee might well be considered the only writer of science who could present the story in understandable fashion. Perhaps, but he would counter that in Eldridge Moores, he enjoyed a tutor of exceptional value to guide him.

The idea of plate tectonics was a revolution in viewing the earth. Previous thinking was nearly all limited to regional, often arcane, activity. Plate tectonics was the first truly global image of the planet's workings. It was elegant, universal, and it explained so much, so well, that fitting it to conditions was almost simple. Plates move, crunch one another, raise mountains, often with spewing volcanoes, and end their career by sinking below the crust. Look at a map of California [easy to do, since there's one at the front of the book]. It all seems so manifestly organized. Parallel mountain ranges running north-south, separated by logically placed valleys. But the Sierra Nevada stands in lofty majesty compared to the Coast Range standing west across the Great Valley. It shouldn't.

According to Moores, that's symptomatic. By plate tectonics' definition, it should be the Coast Range that should rising in reaction to the pressure of the continental movement. And why is the Great Valley so wide if a whole continent is trying to crowd the Sierra Nevada west? Moores suggests that it's because the real western boundary of the North American Plate is around Salt Lake City. The Mormon capital as a Monterey or Santa Barbara requires some reflective thinking, but Moores knows how to read the rocks. And McPhee knows how to tell us what he sees.

What Moores sees could be compared to a geologic highway accident where a string of vehicles reduce order to chaos. Plate tectonics is too simple because it fails to take into account wandering island chains. These are micro-continents with a wanderlust. Moores sees the likelihood of three island chains pranging the West Coast at different times. Each time, instead of being pushed aside by the mass of the North American Plate, they simply attached themselves like limpets. The extra pressure and mass pushed up the High Sierras and the Coast Range. Positioning, erosion and subsidence left the Great Valley, one of the flattest places in the United States, but rich with alluvial soil. The soil produces the world's best wine grapes, and McPhee and Moores justifiably pause in the Sonoma Valley.

McPhee moves from Moores' analysis of mountain building to the study of earthquakes and fault lines in the Golden State. Moores' view of California's disorganization is reinforced by the many directions faults take around the state. Garlock, Hayward, White Wolf are names that impinge on the notoriety of San Andreas. San Andreas, for all its fame, is not a fault, but a melange of fault structures, due to those impinging island arcs. McPhee's timing was fortuitous. As he was preparing the text, the earth was preparing a fitting conclusion to his story. In October of 1989 the earth moved and presented "an invoice of six billion dollars for a few moments of shaking." McPhee, like a diarist recording a life, follows the 'quake from its origins through the state. It's more compelling reading than any mystery novel. Wherever you live, you will come away from this book with an enlightened view of what the earth can tell you. And you will seek out more McPhee.

The dean of literary non-fiction assembles California
In Assembling California, John McPhee has once again shown why he has been described as the dean of literary non-fiction. As he unfolds the geologic story of the state, he manages to seamlessly weave two time scales--geologic and human--into a single compelling story. It is a geology text packaged as literature that will leave you thinking "if all geology texts were written like this, I might have majored in geology." Like his earlier books in the series, starting with Rising from the Plains, he has latched onto an expert geologist and followed him across the globe. One difference is that Rising from the Plains was as much a story of the geologist as the geology. In Assembling California, Eldridge Moores serves primarily as the teacher rather than also as a subject. It isn't always an easy read. When terms like syncline, ophiolite, diabase dikes, and subduction zones are flying at you fast and furiously, even readers with technical backgrounds will frequently have to come up for air. The book cries out for two additions: a glossary and an index. In their absence, you are well advised to take detailed notes. Some of the descriptions would also have benefitted from good illustrations. (The few diagrams included illustrate rather basic points.) Overall, however, McPhee does an excellent job of casting light on what is often considered an arcane subject.

The Prose of Rock and Faultlines
With a precision of language and detail, John McPhee brilliantly evokes the terrain of earthquakes, desert, mountains, and coastline of California. McPhee's guide through the geological history and present-day is Eldridge Moores, a geological professor at UC/Davis who knows the land of California perhaps better than anyone and who can "see through the topography and see how the rocks lie in three dimensions beneath the topography." McPhee is Moores' interpreter, a writer for whom descriptions and metaphor comes as easily as geology does for Moores. Together, they take the reader through the diversity of land formations to form a complex understanding of all the forces that have been at work on this strip of land forming much of the west coast of the United States.

For those only marginally interested in geology and topography, this is a difficult read, though it is well worth sticking with it. I myself read it in chunks, only a single chapter at a time, since any more tested my patience. The writing is superb, however, and the information imparted is both instructional and fascinating. When McPhee writes seemingly simple sentences such as, "There were orchards of carobs, figs, and pistachios, and an understory of prickly pears," he paints an entire countryside in just a few strokes of language. What he does with the drier subject matter of basalt and limestone is extraordinary.
