A man struggles to gain a foothold on a wet rock just below the curtain of water that explodes before him. Yosemite Falls is the highest waterfall in North America, sending water plunging nearly 2,500 feet into the pool at his feet. He seems incongruously puny in scale, bowing to the pulverizing force of the falling curtain of water only a small slip away from disaster. I open the gallery with this image because it symbolizes manís epic struggle against the overwhelming forces of nature. Man continually risks natureís fury at every turn. We must come to respect its power if we are to survive.
