"The choke-cherry, the goose-berry, the buffalo-berry, and black and red currants, are found along the streams and in moist places of the middle and lower altitudes. The meadows and hill-sides are spangled with bright-colored flowers, among which may be noted the bee-larkspur, the columbine, the harebell, the lupine, the evening primrose, the aster, the painted cup, the gentian, and various kinds of euphorbia. It is not uncommon to find daises, buttercups, forget-me-nots, white-ground phlox, and other field flowers flourishing in profusion near the melting snow banks during the month of August. Scarcely a night throughout the year passes without frost, even though the temperature by day is over 80 F., so that all forms of vegetation in the Park grow and bloom under somewhat unusual conditions. Indeed, when ice forms in the water-pails of camping parties during the night, as often happens, and the petals of the flowers become crisp with frost; even then the blooms are not harmed, but thaw out bright and fresh when the hot sun touches them."
The flowers form a most attractive feature of the Park, and give an interesting study of the way in which altitude and temperature affect well known varieties. It is only after a second look that one can trace in the mountain dandelion, huckleberry, and other species a resemblance to those of lower altitudes. The extreme shortness of the season causes vegetation to mature quickly, and before the flush of spring has disappeared from the leaves the palor of autumn makes its appearance.
The mountain grasses are generally abundant in the open country and even in many places among the forests. The writer just quoted says:
"The pasturage on the many open spaces is excellent, the mountain meadows being covered with a mat of nutritious grasses. The predominating variety is the bunch grass, upon which the horses of tourists generally subsist, keeping in good condition without the need of oats. Among other kinds, are the blue joint, fescue, and beard grasses, as well as Alpine timothy, all of which grow luxuriantly."
The early autumns tinge the foliage of the willow parks and other groups of shrubbery with a wealth of color not often seen elsewhere. Even the frost on the grass upon sharp mornings seems to have a peculiar beauty, and one may trace terrestrial rainbows in all the perfection of those set in the sky.
THE PARK IN WINTER.
From the end of September to the end of May the Park is closed to the tourist; that is, the hotels do not receive guests, and camping is too precarious to be attempted. It is generally possible, however, to get into the Park as late as the middle or end of November, very rarely as late as Christmas. In May, the snowfalls are light, but the accumulations of the previous winter render traveling out of the question. With great difficulty the hotel company reaches its nearest hotels as early as May 16. Some of the roads remain impassable fully a month later.
