Every book that anyone sets out on is a voyage of discovery that may discover nothing. Any voyager may be lost at sea, like John Cabot. Nobody can teach the geography of the undiscovered. All he can do is encourge the will to explore, plus impress upon the inexperienced a few of the dos and don'ts of voyaging.

Water is the true wealth in a dry land.

Homesickness is a great teacher. It taught me, during an endless rainy fall, that I came from the arid lands, and like where I came from. I was used to dry clarity and sharpness in the air. I was used to horizons that either lifted into jagged ranges or rimmed the geometrical circle of the flat world. I was used to seeing a long way. I was used to earth colors--tan, rusty red, toned white--and the endless green of Iowa offended me. I was used to a sun that came up over mountains and went down behind other mountains. I missed the color and smell of sagebrush, and the sight of bare ground.

A western buckaroo, I share his scorn for people who go camping by the book, relying on the authority of some half-assed assistant scoutmaster whose total experience outdoors probably consists of two overnight hikes and a weekend in the Catskills. But we have just had that confrontation. The one who goes by Pritchard's book is Sid's wife, and I am wary. It is not my expedition. I am a guest here.

I gave my heart to the mountains the minute I stood beside this river with its spray in my face and watched it thunder into foam, smooth to green glass over sunken rocks, shatter to foam again. I was fascinated by how it sped by and yet was always there; its roar shook both the earth and me.

A political animal can be defined as a body that will go on circulating a petition even with its heart cut out.

National parks are the best idea we ever had. Absolutely American, absolutely democratic, they reflect us at our best rather than our worst.
