The highest and youngest of all the lakes lie nestled in glacier wombs. At first sight, they seem pictures of pure bloodless desolation, miniature arctic seas, bound in perpetual ice and snow, and overshadowed by harsh, gloomy, crumbling precipices. Their waters are keen ultramarine blue in the deepest parts, lively grass-green toward the shore shallows and around the edges of the small bergs usually floating about in them. A few hardy sedges, frost-pinched every night, are occasionally found making soft sods along the sun-touched portions of their shores, and when their northern banks slope openly to the south, and are soil-covered, no matter how coarsely, they are sure to be brightened with flowers. One lake in particular now comes to mind which illustrates the floweriness of the sun-touched banks of these icy gems. Close up under the shadow of the Sierra Matterhorn, on the eastern slope of the range, lies one of the iciest of these glacier lakes at an elevation of about 12,000 feet. A short, ragged-edged glacier crawls into it from the south, and on the opposite side it is embanked and dammed by a series of concentric terminal moraines, made by the glacier when it entirely filled the basin. Half a mile below lies a second lake, at a height of 11,500 feet, about as cold and as pure as a snow-crystal. The waters of the first come gurgling down into it over and through the moraine dam, while a second stream pours into it direct from a glacier that lies to the southeast. Sheer precipices of crystalline snow rise out of deep water on the south, keeping perpetual winter on that side, but there is a fine summery spot on the other, notwithstanding the lake is only about 300 yards wide. Here, on August 25, 1873, I found a charming company of flowers, not pinched, crouching dwarfs, scarce able to look up, but warm and juicy, standing erect in rich cheery color and bloom. On a narrow strip of shingle, close to the water's edge, there were a few tufts of carex gone to seed; and a little way back up the rocky bank at the foot of a crumbling wall so inclined as to absorb and radiate as well as reflect a considerable quantity of sun-heat, was the garden, containing a thrifty thicket of Cowania covered with large yellow flowers; several bushes of the alpine ribes with berries nearly ripe and wildly acid; a few handsome grasses belonging to two distinct species, and one goldenrod; a few hairy lupines and radiant spragueas, whose blue and rose-colored flowers were set off to fine advatage amid green carices; and along a narrow seam in the very warmest angle of the wall a perfectly gorgeous fringe of Epilobium obcordatum with flowers an inch wide, crowded together in lavish profusion, and colored as royal a purple as ever was worn by any high-bred plant of the tropics; and best of all, and greatest of all, a noble thistle in full bloom, standing erect, head and shoulders above his companions, and thrusting out his lances in sturdy vigor as if growing on a Scottish brae. All this brave warm bloom among the raw stones, right in the face of the onlooking glaciers.
As far as I have been able to find out, these upper lakes are snow-buried in winter to a depth of about thirty-five or forty feet, and those most exposed to avalanches, to a depth of even a hundred feet or more. These last are, of course, nearly lost to the landscape. Some remain buried for years, when the snowfall is exceptionally great, and many open only on one side late in the season. The snow of the closed side is composed of coarse granulescompacted and froze into a firm, faintly stratified mass, like the névé of a glacier. The lapping waves of the open portion gradually undermine and cause it to break off in large masses like icebergs, which gives rise to a precipitous front like the discharging wall of a glacier entering the sea. The play of the lights among the crystal angles of these snow-cliffs, the pearly white of the outswelling bosses, the bergs drifting in front, aglow in the sun and edged with green water, and the deep blue disk of the lake itself extending to your feet,--this forms a picture that enriches all your afterlife, and is never forgotten. But however perfect the season and the day, the cold incompleteness of these young lakes is always keenly felt. We approach them with a kind of mean caution, and steal unconfidingly around their crystal shores, dashed and ill at ease, as if expecting to hear some forbidding voice. But the lovesongs of the ouzels and the love-looks of the daisies gradually reassure us, and manifest the warm fountain humanity that pervades the coldest and most solitary of them all.
Chapter 7
The Glacier Meadows
AFTER the lakes on the High Sierra come the glacier meadows. They are smooth, level, silky lawns, lying embedded in the upper forests, on the floors of the valleys, and along the broad backs of the main dividing ridges, at a height of about 8000 to 9500 feet above the sea.
They are nearly as level as the lakes whose places they have taken, and present a dry, even surface free from rock-heaps, mossy bogginess, and the frowsy roughness of rank, coarse-leaved, weedy, and shrubby vegetation. The sod is close and fine, and so complete that you cannot see the ground; and at the same time so brightly enameled with flowers and butterflies that it may well be called a garden-meadow, or meadow-garden; for the plushy sod is in many places so crowded with gentians, daisies, ivesias, and various species of orthocarpus that the grass is scarcely noticeable, while in others the flowers are only pricked in here and there singly, or in small ornamental rosettes.
The most influential of the grasses composing the sod is a delicate calamagrostis with fine filiform leaves, and loose, airy panicles that seem to float above the flowery lawn like a purple mist. But, write as I may, I cannot give anything like an adequate idea of the exquisite beauty of these mountain carpets as they lie smoothly outspread in the savage wilderness. What words are fine enough to picture them? to what shall we like them? The flowery levels of the prairies of the old West, the luxuriant savannahs of the South, and the finest of cultivated meadows are coarse in comparison. One may at first sight compare them with the carefully tended lawns of pleasure-grounds; for they are as free from weeds as they, and as smooth, but here the likeness ends; for these wild lawns, with all their exquisite fineness, have no trace of that painful, licked, snipped, repressed appearance that pleasure-ground lawns are apt to have even when viewed at a distance. And, not to mention the flowers with which they are brightened, their grasses are very much finer both in color and texture, and instead of lying flat and motionless, matted together like a dead green cloth, they respond to the touches of every breeze, rejoicing in pure wildness, blooming and fruiting in the vital light.
Glacier meadows abound throughout all the alpine and subalpine regions of the Sierra in still greater numbers than the lakes. Probably from 2500 to 3000 exist between latitude 36° 30' and 39°, distributed, of course, like the lakes, in concordance with all the other glacial features of the landscape.
On the head waters of the rivers there are what are called "Big Meadows," usually about from five to ten miles long. These occupy the basins of the ancient ice-seas, where many tributary glaciers came together to form the grand trunks. Most, however, are quite small, averaging perhaps but little more than three fourths of a mile in length.
One of the very finest of the thousands I have enjoyed lies hidden in an extensive forest of the Two-leaved Pine, on the edge of the basin of the ancient Tuolumne Mer de Glace, about eight miles to the west of Mount Dana.
Imagine yourself at the Tuolumne Soda Springs on the bank of the river, a day's journey above Yosemite Valley. You set off northward through a forest that stretches away indefinitely before you, seemingly unbroken by openings of any kind. As soon as you are fairly into the woods, the gray mountain-peaks, with their snowy gorges and hollows, are lost to view. The ground is littered with fallen trunks that lie crossed and recrossed like storm-lodged wheat; and besides this close forest of pines, the rich moraine soil supports a luxuriant growth of ribbon-leaved grasses--bromus, triticum, calamagrostis, agrostis, etc., which rear their handsome spikes and panicles above your waist. Making your way through the fertile wilderness,--finding lively bits of interest now and then in the squirrels and Clark crows, and perchance in a deer or bear,--after the lapse of an hour or two vertical bars of sunshine are seen ahead between the brown shafts of the pines, showing that you are approaching an open space, and then you suddenly emerge from the forest shadows upon a delightful purple lawn lying smooth and free in the light like a lake.
