Seite 399 - O • tinct canons, each of which, however, has new wonders to disclose. The Merced River keeps the middle one of these, and its course here is about the same that it was below, or nearly west. It holds this direction nearly up to the base of the Mount Lyell Group, where it heads.
Seite 370 - Whitney was, according to the most reliable calculations, 14,740 feet above the sealevel. At the place where this observation was taken, he was, as near as he was able to estimate, between 300 and 400 feet lower than the culminating point of the mountain, which must therefore somewhat exceed 15,000 feet in height.
Seite 391 - A couple of miles farther up the valley, and on the other side, is the next cluster of peaks, a triple row of summits rising in steps one above the other; these are called the "Three Brothers.
Seite 395 - Illilouette," as it is called by the Indians. From this point the glacial phenomena, and especially the regular and extensive moraines, of that valley are finely displayed. The profile of the Half Dome is best seen from the Sentinel Dome. From near the foot of Sentinel Rock, looking directly across the valley, we have before us, if not the most stupendous feature of the Yosemite, at least the most attractive one, namely, the Yosemite Fall. About the time of...
Seite 402 - In doing this, the river descends, in two miles, over 2000 feet, making, besides innumerable cascades, two grand falls, which are among the greater attractions of the Yosemite, not only on account of their height and the large body of water in the river during...
Seite 98 - In the Coast ranges south of the bay of Monterey, as the bituminous shales are everywhere turned up on edge and have no cover of impervious rock, the inference is unavoidable that flowing wells, or at least those delivering any considerable quantity of liquid petroleum, cannot be expected to be got by boring to any depth ; the probabilities, at least, are decidedly against it. While, therefore, we would not object to a reasonable and prudent expenditure of small amounts to test the question whether...
Seite 399 - Fork, we have on the right hand, just at the entrance of the canyon, that grandest and loftiest mass of the Yosemite Valley, called the Half Dome. This has been in sight, however, through all the upper part of the valley, above the Yosemite Falls, and is a conspicuous point from all the region around.
Seite 401 - The North Dome, on the opposite side of the valley of Tenaya Creek, is another of these rounded masses of granite, of which the concentric structure is very marked. It is three thousand five hundred and sixty-eight feet in elevation above the valley, and is very easy of ascent from the north side. At the angle of the...
Seite 400 - It is an inaccessible crest of granite, rising to the night of four thousand seven hundred and thirty-seven feet* above the valley, the face fronting towards Tenaya Creek being absolutely vertical for two thousand feet down from the summit. The whole appearance of the mass is that of an originally dome-shaped elevation, with an exceedingly steep curve, of which the western half has been split off and has become engulfed.
