- <l>TITLE: Assembling California</l>
- <l>AUTHOR: John McPhee</l>
- <l>PUBLISHER: Farrar, Straus & Giroux; 304 Pages; $21</l>
- </qt>
- <p> THE BOTTOM LINE: A peripatetic author proves that geology
- can be a page turner.
- </p>
- <p> Assembling California is the fourth and final volume of
- John McPhee's "Annals of the Former World" series, his reports
- on the new geology that began running in the New Yorker back in
- the Shawnian Era. That was before the Albion Shift uplifted Tina
- Brown from London and thrust her toward Manhattan, where she
- eventually docked as the magazine's new editor.
- </p>
- <p> McPhee concluded his project at a good time. Brown's
- interests are topical, not topological. Even dedicated
- subscribers to the old New Yorker can be forgiven if their eyes
- lost traction on McPhee's exotic terrain and skidded to the
- cartoons. Those who stayed with "Annals" soon learned to
- appreciate the enterprise. McPhee is a master of expository
- prose.
- </p>
- <p> A lesser writer could not have made a subject as abstruse
- as plate tectonics both intelligible and readable. Seen in four
- dimensions--not least of which is time--the earth appears as
- an endless, slow-motion demolition derby. Untangling cause and
- effect challenges both mind and imagination. Nature has had 4
- billion years to jumble the record, and geologists not even two
- generations to begin to grasp the mechanisms of continental
- drift.
- </p>
- <p> So far, the evidence suggests that earthquakes are
- incremental steps in the movement of the 20 or so lithospheric
- plates that make up the planet's crust. It takes about 50,000
- major jolts to nudge a plate 100 miles. Eldridge Moores, the
- geologist who guides McPhee, believes California was formed when
- a 2,000-mile-long arc of land parked against North America 250
- million years ago.
- </p>
- <p> How does he know? Moores is a specialist in ocean crust,
- which he routinely discovers high and dry in the Sierra Nevada.
- "The whole vast assemblage of transported deep-ocean rock,"
- writes McPhee, "now rests on California like a ship stuck in
- sand, listing thirty degrees to the west." Scientist and writer
- poke through the wreckage. They straddle fault lines and sift
- through road cuts while impatient drivers speed by.
- </p>
- <p> It is soon apparent that Moores and McPhee share more than
- a passion for knowledge. Geology is a way for both men to get
- out of the house. From California they fly to Cyprus, still a
- tectonic mystery, and to Greece, a microplate caught in a
- squeeze between Africa and Europe.
- </p>
- <p> Travel suits the peripatetic nature of the narrative. The
- world is an agora through which Moores and McPhee amble and
- learn. Whenever their exchanges seem about to burst with an
- excess of ophiolites, abyssoliths and subduction zones, McPhee
- relieves the pressure with anecdotes and historical nuggets.
- Included is a tectonic dish of special interest to Californians.
- During the past 2,000 years, part of the San Andreas Fault near
- Los Angeles has been wrenched by 12 major earthquakes. On
- average they occurred 145 years apart. The most recent Big One
- hit in 1857. McPhee makes no predictions but figures his readers
- are smart enough to do their own arithmetic.
