We were building the new Sentinel Bridge in Yosemite Valley in 1992. It was winter time, early morning just before dawn. I was working; it was really quiet. The sun was starting to peek into the valley. I heard some cracking on the Yosemite Falls. I looked up and saw the falls were all frozen. The sun was shining on the ice, and it was beautiful. It was a giant prism of color. All of a sudden, a chunk of ice broke off, and I could hear it crashing down to the ground. It kept breaking and crashing down for about half an hour. These are sights and sounds of Yosemite very few of us get to see.
