It extends up to an elevation of about fifty-five hundred feet. Only a few trees more than a foot in diameter and more than fifty feet high are found higher than four thousand feet above the sea. A few poplars and willows occur on moist places, gradually dwarfing like the conifers. The blue geranium, with leaves red and showy at this time of the year, is perhaps the most telling of the flowering plants. It grows up to five thousand feet or more.
Larkspurs are common, with epilobium, senecio, erigeron, and a few solidagos.
Then come crowberry, and two species of huckleberry, one of them from about six inches to a foot high with delicious berries, the other a most lavishly prolific and contented-looking dwarf, few of the bushes being more than two inches high, counting to the topmost leaf, yet each bearing from ten to twenty or more large berries. Perhaps more than half the bulk of the whole plant is fruit, the largest and finest-flavored of all the huckleberries or blueberries I ever tasted, spreading fine feasts for the grouse and ptarmigan and many others of Nature's mountain people. I noticed three species of dwarf willows, one with narrow leaves, growing at the very summit of the mountain in cracks of the rocks, as well as on patches of soil, another with large, smooth leaves now turning yellow. I may also mention a large mertensia, a fine anemone, a veratrum, six feet high, a large blue daisy, growing up to three to four thousand feet, and at the summit a dwarf species, with dusky, hairy involucres, and a few ferns, aspidium, gymnogramma, and small rock cheilanthes, leaving scarce a foot of ground bare, though the mountain looks bald and brown in the distance like those of the desert ranges of the Great Basin in Utah and Nevada. From this standpoint I counted upwards of two hundred glaciers, while dark-centred luminous clouds with fringed edges hovered and crawled over them, now slowly descending, casting transparent shadows on the ice and snow, now rising high above them, lingering like loving angels guarding the crystal gifts they had bestowed.
