Summer life on the plateau is as effective as a tonic. The altitude varies from seven to nine thousand feet; Rocky Mountain's valley bottoms are higher than the summits of many peaks of celebrity elsewhere. On every hand stretch miles of tumbled meadows and craggy cliffs. Many are the excellent roads, upon which cluster, at intervals of miles, groups of hotels and camps. Here one may choose his own fashion of living, for these hostelries range from the most formal and luxurious hotel to the simplest collection of tents or log cabins around a central log dining structure. Some of these camps are picturesque, the growth of years from the original log hut. Some are equipped with modern comforts; others are as primitive as their beginnings. All the larger resorts have stables of riding horses, for riding is the fashion even with those who do not venture into the mountains. Or, one may camp out in the good old-fashioned way, and fry his own morning bacon over his fire of sticks. Wherever one lives, however one lives, in this broad tableland, he is under the spell of the range. The call of the mountains is ever present. Riding, walking, motoring, fishing, golfing, sitting under the trees with a book, continually he lifts his eyes to their calm heights. Unconsciously he throws them the first morning glance. Instinctively he gazes long upon their gleaming moonlit summits before turning in at night. In time they possess his spirit. They calm him, exalt him, ennoble him. Unconsciously he comes to know them in all their myriad moods. Cold and stern before sunrise, brilliant and vivid in mid-morning, soft and restful toward evening, gorgeously colored at sunset, angry, at times terrifying, in storm, their fascination never weakens, their beauty changes but it does not lessen. Mountains of the height of these live in constant communion with the sky. Mummy Mountain in the north and Longs Peak in the south continually gather handfuls of fleecy cloud. A dozen times a day a mist appears in the blue, as if entangled while passing the towering summit. A few moments later it is a tiny cloud; then, while you watch, it thickens and spreads and hides the peak. Ten minutes later, perhaps, it dissipates as rapidly as it gathered, leaving the granite photographed against the blue. Or it may broaden and settle till it covers a vast acreage of sky and drops a brief shower in near-by valleys, while meadows half a mile away are steeped in sunshine. Then, in a twinkling, all is clear again. Sometimes, when the clearing comes, the summit is white with snow. And sometimes, standing upon a high peak in a blaze of sunshine from a cleared sky, one may look down for a few moments upon the top of one of these settled clouds, knowing that it is sprinkling the hidden valley.
