In the first winter storms the snow is oftentimes soft, and lodges in the dense leafy branches, pressing them down against the trunk, and the slender drooping axis bends lower and lower as the load increases, until the top touches the ground and an ornamental arch is made. Then, as storm succeeds storm and snow is heaped on snow, the whole tree is at last buried, not again to see the light or move leaf or limb until set free by the spring thaws in June or July. Not the young saplings only are thus carefully covered and put to sleep in the whitest of white beds for five or six months of the year, but trees thirty and forty feet high. From April to May, then the snow is compacted, you may ride over the prostrate groves without seeing a single branch or leaf of them. In the autumn they are full of merry life, when Clark crows, squirrels, and chipmunks are gathering the abundant crop of seeds while the deer rest beneath the thick concealing branches. The finest grove in the park is near Mount Conness, and the trail from the Tuolumne soda springs to the mountain runs through it. Many of the trees in this grove are three to four or five feet in diameter and about a hundred feet high.
The mountain hemlock is widely distributed from near the south extremity of the high Sierra northward along the Cascade Mountains of Oregon and Washington and the coast ranges of British Columbia to Alaska, where it was first discovered in 1827. Its northmost limit, so far as I have observed, is in the icy fiords of Prince William’s Sound in latitude 61°, where it forms pure forests at the level of the sea, growing tall and majestic on the banks of the great glaciers, waving in accord with the mountain winds and the thunder of the falling icebergs. Here as in the Sierra it is ineffably beautiful, the very loveliest evergreen in America.
Of the round-headed dicotyledonous trees in the park the most influential are the black and goldcup oaks. They occur in some parts of the main forest belt, scattered among the big pines like a heavier chaparral, but form extensive groves and reach perfect development only in the Yosemite valleys and flats of the main cañons. The California black oak (Quercus Californica) is one of the largest and most beautiful of the Western oaks, attaining under favorable conditions a height of sixty to a hundred feet, with a trunk three to seven feet in diameter, wide-spreading picturesque branches, and smooth lively green foliage handsomely scalloped, purple in the spring, yellow and red in autumn. It grows best in sunny open groves on ground covered with ferns, chokecherry, brier rose, rubus, mints, goldenrods, etc. Few, if any, of the famous oak groves of Europe, however extensive, surpass these in the size and strength and bright, airy beauty of the trees, the color and fragrance of the vegetation beneath them, the quality of the light that fills their leafy arches, and in the grandeur of the surrounding scenery. The finest grove in the park is in one of the little Yosemite valleys of the Tuolumne Cañon, a few miles above Hetch-Hetchy.
