Landscape Evolution Quotes

It is only necessary that man should start a fence that Nature should carry it on and complete it. The farmer cannot plow quite up to the rails or wall which he himself has placed, and hence it often becomes a hedgerow and sometimes a coppice.

As for the flood carving Grand Canyon, why don't they explain to us why the top of the Canyon is 4,000ft higher than where the river (Colorado River) enters the canyon? Why don't they explain to us how rivers miraculously flowed up-hill for millions of years to finally cut the groove deep enough so they could flow downhill?

Of course, the English countryside is completely artificial. It was naturally a forest; they chopped down the trees and made it into what it is now: really a beautiful country.

Streams and mountains never stay the same.

Mountains aren't eternal: even the most imposing massifs are smoothed away by weathering in a few hundred million years or less. Plate tectonics makes new ones, and without it, our future would be flat.

Perhaps I shall not write my account of the Paleolithic at all, but make a film of it. A silent film at that, in which I shall show you first the great slumbering rocks of the Cambrian period, and move from those to the mountains of Wales...from Ordovician to Devonian, on the lush glowing Cotswolds, on to the white cliffs of Dover... An impressionistic, dreaming film, in which the folded rocks arise and flower and grow and become Salisbury Cathedral and York Minster.

There rolls the deep where grew the tree. O earth, what changes hast thou seen! There where the long street roars, hath been The stillness of the central sea. The hills are shadows, and they flow From form to form, and nothing stands; They melt like mist, the solid lands, Like clouds they shape themselves and go.

Nature has many scenes to exhibit, and constantly draws a curtain over this part or that. She is constantly repainting the landscape and all surfaces, dressing up some scene for our entertainment. Lately we had a leafy wilderness; now bare twigs begin to prevail, and soon she will surprise us with a mantle of snow. Some green she thinks so good for our eyes that, like blue, she never banishes it entirely from our eyes, but has created evergreens.
