Yellowstone Park is largely a high plateau, with valleys and mountains, and with somewhat lower areas along the north, west, and southwest boundaries. Much of the park is above 7,000 feet high-Yellowstone Lake is 7,731 feet high-and the continental divide passes through the park. No other large area in the United States has so high an elevation except parts of Colorado and the high Sierra region of California; and this, with its location pretty far north, makes it cool in its short summers and very cold in winter. With its hundreds of geysers, pools of hot water, lakes, clear

nvers and waterfalls, particularly the Lower Falls of the Yellowstone, and the beautifully colored Grand Canyon of the Yellowstone, it is one of the most scenic and interesting areas in the world.
