The Illilouette Falls has a total height of about 370 feet. It is not so impressive as the upper Yosemite, nor so symmetrical as the Vernal, nor so graceful as Bridal Veil, nor so stormy a gush as Nevada; but, as John Muir says, “In the exquisite fineness and richness of texture of its flowing folds, it surpasses them all.” There are many other small falls and cascades in the Yosemite Valley, among them being the Yosemite Gorge Fall and Cascades, the Royal Arch Falls, the Two Sentinel Cascades, and the falls of Cascade and Tamarack Creeks. The Royal Arch Fall in time of high water is beautiful; and the Two Sentinel Cascades, 3,000 feet high, are also wonderful spectacles. By the middle of summer, however, these have diminished so greatly that they are hardly noticeable. The volume of water in the falls of the Valley varies greatly at different times--and so do the accounts of the altitude of the cataracts. You may have Illilouette Falls anywhere from 370 to 600 feet high, and the Upper Yosemite Falls anywhere from 1,400 to 1,600 feet high--just according to whom you ask. There is a like variation in the statements of the altitude of summits, and the size and age of the giant trees. Our figures are taken from the documents issued by the Department of the Interior of the United States Government.

[Illustration: FROM A WATER COLOR PAINTING EL CAPITAN, YOSEMITE NATIONAL PARK] _THE YOSEMITE VALLEY_ _The Summits_ THREE First in impressiveness and second only to the waterfalls in beauty, are the summits of the Yosemite Valley. Of all these summits El Capitan stands preëminent, although it is not the highest; that honor belonging to Cloud’s Rest. El Capitan, probably the largest mass of single rock in the world, stands on the north wall of the valley. It rises almost vertically 3,600 feet above the plain, and it is nearly rectangular in shape. Its two vast faces measure about 160 acres each in area. You can judge of its size by singling out what appears to be a green bush which took root and is growing in a shallow niche far up on the face of the rock. That green bush is called “The Lone Pine,” and _it is 150 feet high_. El Capitan stands like a grand old veteran, and it is one of the most imposing monuments that nature has left to show the terrific forces which at one time worked their will with this planet. Its summit may be reached by a long and arduous journey, which is seldom undertaken.
