South Rim, Grand Canyon, Arizona

I bought the 'bible' of the Grand Canyon story of discovery, John Wesley Powell's, 'The Exploration of the Colorado River and its Canyon', here is some of his writing:

• The wonders of the Grand Canyon cannot be adequately represented in symbols of speech, nor by speech itself.
• The traveler on the brink looks from afar and is overwhelmed with the sublimity of massive forms…
• (water) can do much work in centuries of centuries.
