Half Dome may be one of the most photographed sights in America. What happened to the other half? Geologists say that there never was another half--that this is the whole thing, though other dome shaped peaks in Yosemite are "whole". My mother climbed Half Dome--not something that I could ever have imagined of her. Maybe that hike was the cause of her later fear of heights.
You can see that the skies over Yosemite when we visited last month were clear and blue. You can also see hundreds of skies from around the world at SkyWatch.
