Numerous waterfalls are found here, from cascades a few feet in height to cataracts having twice the leap of Niagara; lakes lie deeply embosomed among the high peaks or the heavy forests, and one of them, twenty miles in length and a mile and a half above the ocean, is now being navigated--think of it!--by motor-boats; thousands of miles of crystal trout-streams, kept supplied with trout by the government hatcheries, radiate in every direction; a natural glass cliff, an Indian quarry for arrow-heads in the ancient days, towers above a lake formed at its base by the wise and cunning beavers. There is, too, a low mountain of pure sulphur, with beautiful boiling sulphur-pools splashing at its foot; and, in contrast to these, there is a gruesome volcano of mud belching from a dark, malodorous cavern, while almost beside this is a beautiful, clear pool of hot water formed by a stream flowing from beneath a green Gothic arch. The wonderful cañons, exhibiting such different phases of nature's sublime handiwork, awe the beholder. One shows the marvelous way in which lava, cooling, arranges itself in massive, black, symmetric slabs and columns; these enclose a beautiful fall that adds a touch of lightness and beauty. The Grand Cañon is the most startling and extraordinary example of color harmony and nature sculpture to be found in the universe. A Japanese, in the poetic imagery of his race, has said that these brilliant cañon walls have caught and emblazoned upon their mural precipices the sunsets of all the yesterdays--a beautiful conception. One stands awed to silence in the presence of "Nature's immensities" seen here and is almost overwhelmed by the profound splendors and majestic glories of this cañon. In another respect this park land stands in a category by itself. By federal enactment all of the Yellowstone Park proper and some additional territory bordering it has been made a vast national game-preserve, something not originally planned. As settlement has increased and the valleys have become occupied by farmers and ranchmen, the game has been forced into the higher valleys and parks of the mountains, or into their remote recesses. Here, within the park boundaries, deer, elk, antelope, bears, mountain-sheep, moose, bison, and the smaller game, birds (between 150 and 200 species), and fur-bearing animals, have a refuge where no hunter or trapper penetrates and danger rarely intrudes. In the Jackson Lake country, hunting is allowed for a limited period. There are thousands of these various animals that know they are absolutely immune from harm by man when within the bounds of this park. Most of them have never seen a dog nor heard the sound of a rifle. Under these conditions their natural timidity is greatly lessened, and many of them, even bears, become surprisingly tame.
