“This is not wilderness for designation or for a park. Not a scenic wilderness and not one good for fishing or the viewing of wildlife. It is wilderness that gets into your nostrils, that runs with your sweat. It is the core of everything living, wilderness like molten iron.”

“A trademark of something that works well, the cat body has hardly changed since its inception. Like with today's cats, their digestive systems could handle only flesh. The lesson of the cat is that if you are to become a full-fledged carnivore, you have to commit everything to it. A house cat fed vegetarian food will shrivel and die.”

“The elk that you glimpse in the summer, those at the forest edge, are survivors of winter, only the strongest. You see one just before dusk that summer, standing at the perimeter of the meadow so it can step back to the forest and vanish. You can't help imagining the still, frozen nights behind it, so cold that the slightest motion is monumental. I have found their bodies, half drifted over in snow, no sign of animal attack or injury. Just toppled over one night with ice working into their lungs. You wouldn't want to stand outside for more than a few minutes in that kind of weather. If you lived through only one of those winters the way this elk has, you would write books about it. You would become a shaman. You would be forever changed. That elk from the winter stands there on the summer evening, watching from beside the forest. It keeps its story to itself.”

“The wilderness and the idea of wilderness is one of the permanent homes of the human spirit.”

“Like any stage of the hydrologic process, we have our own peculiarities, our organs making us nothing more than water pools or springs of bizarre shape, filled with pulsing tubes and chambers.”

“Plans to protect air and water, wilderness and wildlife, are in fact plans to protect man.”

“There are so many of us now that we threaten to devour the world with our touching, starting with the things we adore most. At the same time, we obviously yearn for contact, and I fear what would happen if we were cut off from a distinctive, on-the-ground relationship with the past.”
