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.
The mountain live-oak, or goldcup oak (Quercus chrysolepis), forms extensive groves on earthquake and avalanche taluses and terraces in cañons and Yosemite valleys, from about three to five thousand feet above the sea. In tough, sturdy, unwedgeable strength this is the oak of oaks. In general appearance it resembles the great live-oak of the Southern states. It has pale gray dark, a short, uneven, heavily buttressed trunk which usually divides a few feet above the ground into strong wide-reaching limbs, forming noble arches, and ending in an intricate maze of small branches and sprays, the outer ones frequently drooping in long tresses to the ground like those of the weeping willow, covered with small simple polished leaves, making a canopy broad and bossy, on which the sunshine falls in glorious brightness. The acorn cups are shallow, thick-walled, and covered with yellow fuzzy dust. The flowers appear in May and June with a profusion of pollened tresses, followed by the bronze-colored young leaves.
