One day's exposure to mountains is better than cartloads of books. See how willingly Nature poses herself upon photographers' plates. No earthly chemicals are so sensitive as those of the human soul.

In every walk with nature one receives far more than he seeks.

These temple destroyers, devotees of ravaging commercialism, seem to have a perfect contempt for Nature, and, instead of lifting their eyes to the God of the mountains, lift them to the Almighty Dollar.

Keep close to Nature's heart... and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.

No synonym for God is so perfect as Beauty. Whether as seen carving the lines of the mountains with glaciers, or gathering matter into stars, or planning the movements of water, or gardening - still all is Beauty!

Over the summit, I saw the so-called Mono desert lying dreamily silent in the thick, purple light -- a desert of heavy sun-glare beheld from a desert of ice-burnished granite.

Any fool can destroy trees, they cannot run away.
