Despite the recurrence of events in which the debris-basin system fails in its struggle to contain the falling mountains, people who live on the fron… - John McPhee

Only once in the historical record has a jump on the San Andreas exceeded the jump of 1906. In 1857, near Tejon Pass outside Los Angeles, the two sides shifted thirty feet.

No one will ever write in just the way that you do, or in just the way that anyone else does. Because of this fact, there is no real competition between writers. What appears to be competition is actually nothing more than jealousy and gossip. Writing is a matter strictly of developing oneself. You compete only with yourself. You develop yourself by writing.

It has been Anita’s style as a geologist to begin with an outcrop and address herself to history from there — to begin with what she can touch, and then to reason her way back through time as far as she can go. A river conglomerate, as tangible rock, unarguably presents the river. The river speaks of higher ground. The volume of sediment that the river has carried can imply a range of mountains. To find Precambrian jaspers in the beds of younger rivers means that the Precambrian, the so-called basement rock, was lifted to form the mountains. These are sensible inferences drawn cleanly through an absence of alternatives. To go back in this way, retrospectively, from scene to shifting scene, is to go down the rock column, groping toward the beginning of the world. There is firm ground some of the way. Eventually, there comes a point where inference will shade into conjecture. In recesses even more remote, conjecture may usurp the original franchise of God.
