Surely such an impressive alternation of rivers, forests, lakes, canyons, and mountains is in itself complete. Someone has said, “Yellowstone has everything except a cave and a glacier.” Actually, there are caves and glaciers in the Park’s environs, but the most unique feature of all this Wonderland is its thermal activity. Thousands of hot springs and hundreds of geysers reveal strange secrets of the inner earth. Mammoth Hot Springs Terraces represents the actual process of a mountain turning inside out. Yellowstone Park is roughly located between longitude 110° W. and 111° W. and latitude 44° N. and 45° N. In respect to Wyoming, the Park is located in the northwestern corner, encroaching slightly upon Montana and Idaho. The area comprehends three thousand, four hundred and seventy-two square miles, and the average elevation is eight thousand feet above sea level. Occupying a central portion of the Rockies’ greatest girth, the Park’s scenic position is most strategic. From the top of Mt. Washburn a majestic rock-ribbed panorama is disclosed. It is indeed a vast area, surrounded by lofty mountain ranges, some of whose towering peaks are reflected in Lake Yellowstone. This comprehensive view reminds one of a gigantic amphitheatre or, from another angle, a colossal orange juicer with the Yellowstone River as its spigot. At the river’s outlet from the Park at North Gate the elevation is five thousand, three hundred and fourteen feet above sea level, whereas the maximum height of eleven thousand, three hundred and sixty feet is achieved on the summit of Eagle Peak on the southeastern boundary.[4] Cartographers have segregated the most conspicuous elevations into seven plateaus, three ranges, four ridges, and several minor units of mountains and hills.[5] Thirty-two mountain peaks loom above the ten-thousand-foot level, and another six exceed the eleven-thousand-foot scale.[6] The Continental Divide winds among the Park’s southern plateaus in the manner of a serpent. From these circumstances, Yellowstone Park has become truly the wondrous land of water and the source of that life-giving liquid to lands hundreds of miles away in all directions. Nowhere else does water so well display its varied charms. From the Divide’s snowy, timber-rimmed pockets, icy rivulets flow into sylvan pools, thence to rushing rivers with thundering waterfalls. Other water issues from steaming vents and towering geysers connected with the earth’s internal heat and weaves vaporous trails into streams called warm or fire rivers.[7]
