First of course is Yosemite Falls, in full glory of spring. The falls were booming across the valley, and they were beautiful. They constitute one of the tallest waterfalls in the world (somewhere around 5th to 7th place by most measures) with a total drop of 2,425 feet. The falls are a fine example of a hanging valley, caused when the much larger Merced Glacier cut deeper than the smaller glacier of Yosemite Creek.
Yosemite Falls were once much less interesting. The tree-filled cleft to the left of the Upper Falls was the original channel of Yosemite Creek and there was a steep cascade rather than a sheer drop. Some glacial debris (a moraine) along the top of the cliff blocked the channel, forcing the river over the cliff at the present site.
The high approach to the valley from Big Oak Flat and Crane Flat includes some nice overlooks of the Merced River Valley and Bridalveil Fall along with the Cathedral Rocks and the Leaning Tower (the one sunlit cliff).
Half Dome is visible from many places in the valley, but one of my favorites is the middle of the Curry Village parking lot! The only difficulty is a lone telephone wire crossing the lot that keeps getting in the picture. The clouds were playing hide-and-seek with the summit of the dome.
