On either side of Po-ho-no the sky-line of the precipice is magnificently varied. The fall itself cuts a deep gorge into the crown of the battlement. On the southwest border of the fall stands a nobly bold, but nameless rock, three thousand feet in height. Near by is Sentinel Rock, a solitary truncate pinnacle, towering to thirty-three hundred feet. A little farther are "Eleachas," or "The Three Brothers," flush with the front-surface of the precipice, but their upper posterior bounding-planes tilted in three tiers, which reach a height of thirty-four hundred and fifty feet. One of the loveliest places in the Valley is the shore of Lake Ah-wi-yah,--a crystal pond of several acres in extent, fed by the north fork of the Valley-stream, and lying right at the mouth of the narrow strait between the North and South Domes. By this tranquil water we pitched our third camp, and when the rising sun began to shine through the mighty cleft before us, the play of color and _chiaroscuro_ on its rugged walls was something for which an artist apt to oversleep himself might well have sat up all the night. No such precaution was needed by ourselves. Painters, sages, and gentlemen at large, all turned out by dawn; for the studies were grander, the grouse and quail plentier, and the butterflies more gorgeous than we found in any other portion of the Valley. After passing the great cleft eastward, I found the river more enchanting at every step. I was obliged to penetrate in this direction entirely on foot,--clambering between squared blocks of granite dislodged from the wall beneath the North Dome, any one of which might have been excavated into a commodious church, and discovering, for the pains cost by a reconnoissance of five miles, some of the loveliest shady stretches of singing water and some of the finest minor waterfalls in our American scenery.
