Yosemite is awesome. The valley was carved out of granite by glaciers, leaving smooth domes and sheer cliffs, which makes for lots of waterfalls. On the first day we toured Yosemite Valley, and saw
On the second day, we went to Glacier Point, which is on the South rim of the valley, and to the Mariposa Grove of Big Trees (more sequoias). From Glacier Point, at 7000 feet, you can see Half Dome really well
They cut holes in two of the sequoias in Yosemite in 1895, and built a road through one of them. That tree fell down in 1969, no doubt helped by having a big hole cut in it, and so they didn't cut another, but the second is still standing.
There are more Big Tree pictures, but as someone said to us, once you've seen one 270-foot, 3,000-year-old tree, you've sort of seen them all. But they are awesome.
