May 20, 1863: White River
[Today] the rain stopped and we rode from Greenhorn to Tailholt (a good sample of Californian names) over a very rough road, up and down, sometimes by wagon road and sometimes by trail.
On the west slope of the Sierra there is more timber—scattered oaks and pines—and some of the slopes are covered with chaparral. There is some more grass over the hills, and all tells of a moister climate. From some of the ridges we had wide and magnificent views of the foothills and the great valley on the west, but the coast ranges were shut out by the hazy air. Tailholt is on White River, among the hills, but we struck a very comfortable place to stop.All these streams flow out into the valley through wild, impassable canyons, but in the mountains the valleys often spread out into little basins, some of which are of exceeding beauty; but being made of granite sand, none are very fertile. We passed two such, the Posé Flat and Little Posé Flat, both little basins, green on the bottom, with a clear stream of water, and fine old oak trees.
