And here the canyon is all broadly open again--the floor luxuriantly forested with pine, and spruce, and silver fir, and brown-trunked libocedrus. The walls rise in Yosemite forms, and Tenaya Creek comes down seven hundred feet in a white brush of foam. This is a little Yosemite valley. It is about two thousand feet above the level of the main Yosemite, and about twenty-four hundred below Lake Tenaya.

I found the lake frozen, and the ice was so clear and unruffled that the surrounding mountains and the groves that look down upon it were reflected almost as perfectly as I ever beheld them in the calm evening mirrors of summer. At a little distance, it was difficult to believe the lake frozen at all; and when I walked out on it, cautiously stamping at short intervals to test the strength of the ice, I seemed to walk mysteriously, without adequate faith, on the surface of the water. The ice was so transparent that I could see through it the beautifully wave-rippled, sandy bottom, and the scales of mica glinting back the down-pouring light. When I knelt down with my face close to the ice, through which the sunbeams were pouring, I was delighted to discover myriads of Tyndall's six-rayed water flowers, magnificently colored.

A grand old mountain mansion is this Tenaya region! In the glacier period it was a mer de glace, far grander than the mer de glace of Switzerland, which is only about half a mile broad. The Tenaya mer de glace was not less than two miles broad, late in the glacier epoch, when all the principal dividing crests were bare; and its depth was not less than fifteen hundred feet. Ice streams from Mounts Lyell and Dana, and all the mountains between, and from the nearer Cathedral Peak, flowed hither, welded into one, and worked together. After eroding this Tanaya Lake basin, and all the splendidly sculptured rocks and mountains that surround and adorn it, and the great Tenaya Canyon, with its wealth of all that makes mountains sublime, they were welded with the vast South, Lyell, and Illilouette glaciers on one side, and with those of Hoffman on the other--thus forming a portion of a yet grander mer de glace in Yosemite Valley.

I reached the Tenaya Canyon, on my way home, by coming in from the northeast, rambling down over the shoulders of Mount Watkins, touching bottom a mile above Mirror Lake. From thence home was but a saunter in the moonlight.

After resting one day, and the weather continuing calm, I ran up over the left shoulder of South Dome and down in front of its grand split face to make some measurements, completed my work, climbed to the right shoulder, struck off along the ridge for Cloud's Rest, and reached the topmost heave of her sunny wave in ample time to see the sunset.

Cloud's Rest is a thousand feet higher than Tissiack. It is a wavelike crest upon a ridge, which begins at Yosemite with Tissiack, and runs continuously eastward to the thicket of peaks and crests around Lake Tenaya. This lofty granite wall is bent this way and that by the restless and weariless action of glaciers just as if it had been made of dough. But the grand circumference of mountains and forests are coming from far and near, densing into one close assemblage; for the sun, their god and father, with love ineffable, is glowing a sunset farewell. Not one of all the assembled rocks or trees seemed remote. How impressively their faces shone with responsive love!

I ran home in the moonlight with firm strides; for the sun-love made me strong. Down through the junipers; down through the firs; now in jet shadows, now in white light; over sandy moraines and bare, clanking rocks; past the huge ghost of South Dome rising weird through the firs; past the glorious fall of Nevada, the groves of I llilouette; through the pines of the valley; beneath the bright crystal sky blazing with stars. All of this mountain wealth in one day!--one of the rich ripe days that enlarge one's life; so much of the sun upon one side of it, so much of the moon and stars on the other.
