figure in the calculations of the period that they were not even protected in the national park until 1894, when hunting had reduced the buffalo to twenty-five animals. Even in these days of enlightenment and appreciation the great majority of people think of the Yellowstone only as an area enclosing geysers. There are tourists so possessed with this idea that they barely glance at the canyon in passing. I have heard tourists refuse to walk to Inspiration Point because they had already looked over the rim at a convenient and unimpressive place. Imagine coming two thousand miles to balk at two miles and a half to the only spectacle of its kind in the world and one of the world's great spectacles at that! As for the animals, few indeed see any but the occasional bears that feed at the hotel dumps in the evening. The Yellowstone National Park lies in the recesses of the Rocky Mountains in northwestern Wyoming. It slightly overlaps Montana on the north and northwest, and Idaho on the southwest. It is rectangular, with an entrance about the middle of each side. It is the largest of the national parks, enclosing 3,348 square miles. It occupies a high plain girt with mountains. The Absarokas bound it on the east, their crest invading the park at Mount Chittenden. The Gallatin Range pushes into the northwestern corner from the north. The continental divide crosses the southwestern corner over the lofty Madison Plateau and the ridge south of Yellowstone Lake. Altitudes are generally high. The plains range from six to eight thousand feet; the mountains rise occasionally to ten thousand feet. South of the park the Pitchstone Plateau merges into the foothills of the Teton Mountains, which, thirty miles south of the southern boundary, rise precipitously seven thousand feet above the general level of the country. Though occupying the heart of the Rocky Mountains, the region is not of them. In no sense is it typical. The Rockies are essentially granite which was forced molten from the depths when, at the creation of this vast central mountain system, lateral pressures lifted the earth's skin high above sea-level, folded it, and finally eroded it along the crest of the folds. In this granite system the Yellowstone is a volcanic interlude, and of much later date. It belongs in a general way to the impulse of volcanic agitation which lighted vast beacons over three hundred thousand square miles of our northwest. The Cascade Mountain
