The charm of the mountains from below may satisfy many, but sooner or later temptation is sure to beset. The desire comes to see close up those monsters of mystery. Many, including most women, ignorant of rewards, refuse to venture because they fear hardship. "I can never climb mountains in this rarefied air," pleads one, and in most cases this is true; it is important that persons unused to the higher altitudes be temperate and discreet. But the lungs and muscles of a well-trained mountain horse are always obtainable, and the least practice will teach the unaccustomed rider that all he has to do is to sit his saddle limply and leave everything else to the horse. It is my proud boast that I can climb any mountain, no matter how high and difficult, up which my horse can carry me. And so, at last and inevitably, we ascend into the mountains. IV The mountains within the park fall naturally in two groupings. The Front Range cuts the southern boundary midway and runs north to Longs Peak, where it swings westerly and carries the continental divide out of the park at its northwestern corner. The Mummy Range occupies the park's entire north end. The two are joined by a ridge 11,500 feet in altitude, over which the Fall River Road is building to connect the east and the west sides of the park. The lesser of these two, the Mummy Range, is a mountain group of distinguished beauty. Its climax is an arc of gray monsters, Ypsilon Mountain, 13,507 feet, Mount Fairchild, 13,502 feet, Hagues Peak, 13,562 feet, and Mount Dunraven, 12,326 feet; these gather around Mummy Mountain with its 13,413 feet. A noble company, indeed, herded in close comradeship, the centre of many square miles of summits scarcely less. Ypsilon's big Greek letter, outlined in perpetual snow, is one of the famous landmarks of the northern end. Hagues Peak supports Hallett Glacier, the most interesting in the park. Dunraven, aloof and of slenderer outline, offers marked contrast to the enormous sprawling bulk of Mummy, always portentous, often capped with clouds. The range is split by many fine canyons and dotted with glacial lakes, an undeveloped wilderness designed by kindly nature for summer exploration. But it is the Front Range, the snowy pinnacled rampart, which commands profoundest attention.
