High up in the Rocky Mountains are lakes which shine as brightly as dewdrops in a garden. These mountains are a vast hanging garden in which flowers and waterfalls, forests and lakes, slopes and terraces, group and mingle in lovely grandeur. Hundreds of these lakes and tarns rest in this broken topography. Though most of them are small, they vary in size from one acre to two thousand acres. Scores of these lakes have not been named. They form a harmonious part of the architecture of the mountains. Their basins were patiently fashioned by the Ice King. Of the thousand or more lakes in the Colorado mountains only a few are not glacial. The overwhelming majority rest in basins that were gouged and worn in solid rock by glaciers. John Muir says that Nature used the delicate snowflake for a tool with which to fashion lake-basins and to sculpture the mountains. He also says: "Every lake in the Sierra CRYSTAL LAKE, A TYPICAL GLACIER LAKE These lakes are scattered through the high mountains of Colorado, the greater number lying between the altitudes of ten thousand and twelve thousand feet. Few were formed above the altitude of twelve thousand, and most of those below ten thousand now are great flowerpots and hold a flower-illumined meadow or a grove. Timber-line divides this lake-belt into two nearly equal parts. Many are small tarns with rocky and utterly wild surroundings. Circular, elliptical, and long, narrow forms predominate. Some lie upon a narrow terrace along the base of a precipice. Many are great circular wells at the bottom of a fall; others are long and narrow, filling caÑons from wall to wall. Glaciers the world over have been the chief Nature's ways are interestingly complicated. Both the number and the location of many of these glacier lakes are due in part to the prevailing direction of the wind during the last glacial epoch. This is especially true of those in the Snowy Range of the Rocky Mountains, which fronts the Great Plains. The majority of the lakes in this range are situated on its eastern slope. Westerly winds undoubtedly prevailed on these mountains during the de Westerly winds still blow strongly, sometimes for weeks, and the present scanty snowfall is largely swept from the western slopes and deposited on the eastern side. So far as I know, Though these lakes vary in shape and size, and though each is set in a different topography, many have a number of like features and are surrounded with somewhat similar verdure. A typical lake is elliptical and about one fifth of a mile long; its altitude about ten thousand feet; its waters clear and cold. A few huge rock-points or boulders thrust through its surface near the outlet. A part of its circling shore is of clean granite whose lines proclaim the former presence of the Ice King. Extending from one shore is a dense, dark forest. One stretch of low-lying shore is parklike and grassy, flower-crowded, and dotted here and there with a plume of spruce or fir. By the outlet is a filled-in In summer, magpies, woodpeckers, nuthatches, and chickadees live in the bordering woods. In the willows the white-crowned sparrow builds. By the outlet or in the cascades above or below is the ever-cheerful water-ouzel. The solitaire nesting near often flies across the lake, filling the air with eager and melodious song. Along the shore, gentians, columbines, paintbrushes, larkspur, and blue mertensia often lean over the edge and give the water-margin the beauty of their reflected colors. These lakes above the limits of tree-growth do not appear desolate, even though stern peaks rise far above. The bits of flowery meadow or moorland lying close or stretching away, the songful streams arriving or departing, soften their coldness and give a welcome to their rock-bound, crag-piled shores. Mountain sheep are often visitors. They come to drink, or to feed and play in the sedgy meadow near by. Ptarmigan have their homes here, and all around them nest many birds from the southland. Into these lakes swift waters run, and here the snowy cataract leaps in glory. From the overshadowing cliffs, flattened and lacy streams flutter down. During the summer there is the ever-flowing harmony, the endless animation, of falling water; and in winter there is the silent and architectural symphony of the frozen waterfall. Many lakes during summer are partly edged with inthrusting snow and ice piles; from time to time fragments of these piles break away and become miniature icebergs in these small arctic seas. Although filled with the purest and clearest water, from a distant height they often appear to contain a brilliant heavy liquid. Under different lights and from different points of view they are emerald, opal, inky black, violet, indigo-blue, and sea-green. I have approached one from a high distant point, and as I descended and waveringly advanced, the lake took on a number of deep colors, each melting like a passing shadow from one into the other. Occasionally, too, it almost vanished in dull gray or flashed up in molten silver. The colors shown Below the timber-line these lakes are more appealing, and many in the midst of groves and meadows help to form delightful wild parks. Others are hidden away in black forests; tall, crowding firs and spruces rise from their edges and hide them completely, even when one is only a yard or two from their shores. I camped for a week within a stone's throw of one of these forest-embowered gems without suspecting its presence. Returning to camp one evening from an encircling ramble, I was startled by stepping into a lake-edge. For a moment I was puzzled. Instinctively I felt that my camp was about the width of the lake ahead of me. Although I felt certain of my bearings, my mental processes were such that I was unwilling to trust this strange lake. Instead of walking around its poetic shore, I lashed two water-soaked logs Elements of peculiar attractiveness are combined in the lakes that are situated along the timber-line. Some have a treeless mountain or a rugged snow-piled peak rising boldly behind, and an acre or so of meadow between one shore and the forest. A segment of wind-distorted trees, a few enormous rock domes, a fine pile of boulders, and a strip of willow with clumps of spruces and firs combine to give a charming border. Among the best known of these Colorado lakes are Grand, Trapper's, Bierstadt, Trout, San Cristoval, Chicago, Thunder, Silver, Moraine, and Twin Lakes. Grand Lake, probably the largest, is about three miles long by one mile wide. Its basin appears to be largely due to a morainal dam. The San Cristoval basin appears to have been formed by a mud stream which blockaded a mountain valley. The lakes of the Long's Peak region are my favorites. These are numerous and show a variety of forms. The alpine lakes in the mountains of the West are but little known to travelers. Many Western people appreciate the beauty of the Swiss and Italian lakes but do not even know of the existence of the shining lakes in their own mountains. But the unexcelled beauty and grandeur of these lakes, their scenic surroundings, and the happy climate in which they repose will in due time give them fame and bring countless travelers to their shores. In exploring the mountains I have often camped on a lake-shore. These camps were conveniently situated for the exploration of neighboring slopes and the valley below; or for making excursions to the more rugged scenes,—the moraines, snow-fields, cirques, and peaks Many times camp was so situated that splendid sunsets or the lingering pink and silver afterglow were at their best behind a broken sky-line ridge. My camp-fire was reflected in the lake, which often sparkled as if enamel-filled with stars. Across one corner lay softly the inverted Milky Way. Shooting stars passed like white rockets through the silent waters. The moon came up big and yellow from behind a crag and in the lake became a disc of gold. Many a night the cliffs repeated the restlessness of the wind-shaken water until the sun quieted all with light. During the calm nights there were hours of almost unbroken silence, though at times and faintly a far-off waterfall could be heard, the bark of a fox sounded across the lake, or the weird and merry cries of the coyote were Occasionally I remained in camp almost motionless from early morning until the stars of evening filled the lake, enjoying the comings and goings and social gatherings of the wilderness folk. These lakes, if frozen during calm times, have ice of exceeding clearness and smoothness. In early winter this reflects peak, cloud, and sky with astonishing faithfulness. In walking across on this ice when the reflective condition was at its best, I have marveled at my reflection, or that of Scotch, my dog, walking on what appeared to be the surface of the water. The lakes above timber-line are frozen over about nine months of the year, some of them even longer. Gravity and water are filling with dÉbris and sediment these basins which the glaciers dug. Many lakes have long since faded from the landscape. The earthy surface as it emerges above the water is in time overspread with a carpet of plushy sedge or grass, a tangle of willow, a grove of aspen, or a forest of pine or spruce. The rapidity of this filling is dependent on a number of things,—the situation of the lake, the stability of the watershed, its relation to forests, slopes, meadows, and other lakes, which may intercept a part of the down-coming sediment or wreckage. This filling material may be deposited evenly over the bottom, the lake steadily becoming shallower, though maintaining its original size, with its edge clean until the last; or it may be heaped at one end or piled along one side. In some lakes the entering stream builds a slowly extending delta, which in time gains the surface and extends over the entire basin. In other lakes a side stream may form an expanding dry delta which the grass, Landslides, large and small, often plunge into these lakes. One of the largest rock avalanches that I ever saw made one wild leap into Chasm Lake and buried itself. This was about the middle of June. This glacier lake is on the eastern side of Long's Peak and is in a most utterly wild place. The lake was still covered with thick ice, and on the ice the snow lay deep. But spring was melting and loosening things in the alpine heights. As I stood on a talus slope above This avalanche was formed of a quantity of broken granite sufficient to load a number of freight-trains. It smashed through the icy cover of the lake. The effect was like a terrific explosion. Enormous fragments of ice were thrown into the air and hurled afar. Great masses of water burst explosively upward, as if the entire filling of water had been blown out or had leaped out of its basin. The cliffs opposite were deluged. The confused wind-current which this created shredded and separated much Water and ice are incessantly at work tearing down the heights. Water undermines by washing away the softer parts and by leaching. Every winter ice thrusts its expansive wedge into each opening. Places are so shattered by this explosive action that thousands of gallons of water are admitted. This collects in openings, and the following winter the freezing and forcing continues. During the winter the irresistible expansion of freezing water thus pushes the rocks and widens the openings with a force that is slow but powerful. Winter by winter rocks are moved; summer by summer the water helps enlarge the opening. Years or centuries go by, and at last during a rainy time or in the spring thaw a mass slips away or falls over. This may amount to only a few pounds, or it may be a cliff or even a mountain-side. The long ice-ages of the earth appear to have their sway, go, and return. These alternate with A Mountain Pony |
