spring, and plentifully spattered with snow all summer long, the vast, bare granite masses, from which, in fact, the Rocky Mountains got their name, are beautiful beyond description. They are rosy at sunrise and sunset. During fair and sunny days they show all shades of translucent grays and mauves and blues. In some lights they are almost fairylike in their delicacy. But on stormy days they are cold and dark and forbidding, burying their heads in gloomy clouds from which sometimes they emerge covered with snow.

FAUNA AND FLORA

The national park is a sanctuary for wildlife. Animals and birds are protected from hunting. Living trees may not be cut or injured. Flowers may not be picked. The cooperation of visitors is requested, in order that the wildlife of the park may be protected, that the flowers may continue in their present abundance, and that the forests of the park may not suffer injury from fire or other cause.

Animals

The lofty rocks are the natural home of the celebrated Rocky Mountain sheep, or bighorn. This animal is much larger than any domestic sheep. It is powerful and wonderfully agile. When fleeing from enemies these sheep, even the lambs, make remarkable descents down seemingly impossible slopes. They do not land on their curved horns, as many persons declare, but upon their four feet held closely together. Landing on some nearby ledge, which breaks their fall, they immediately plunge downward again to another ledge, and so on till they reach good footing in the valley below. They also ascend slopes surprisingly steep. They are more agile even than the celebrated chamois of the Swiss Alps, and are larger, more powerful, and much handsomer. A flock of a dozen or more mountain sheep making their way along the volcanic flow which constitutes Specimen Mountain in Rocky Mountain National Park is an unforgettable sight.

The beaver, whose dams and other structures, both old and new, found along most streams at middle altitudes, are rarely seen except at night or very early morning. Elk occur in numerous places, and deer which are widely distributed are commonly seen. Coyotes and brown or black bear are occasionally seen, but these, like the mountain lion, bobcat, and small carnivorous animals, are not only rare, but so wary that they are seldom seen by visitors.

Among smaller animals, the most familiar are the marmot or woodchuck, Freemont or pine squirrel, three kinds of chipmunks, and the interesting little cony or pika, which lives among the rocks on high mountains and is more often heard than seen. In all, over 60 species of mammals live in the park.

Birds

The commonest species are the western robin, the beautiful mountain bluebird, and, at middle elevations, the chickadee and junco. The hermit thrush and the solitaire, generally classed among the finest songbirds in the world, are both fairly common in suitable localities; and but little inferior to these in musical performance are the purple finch, ruby-crowned kinglet, western meadowlark, and rock and canyon wrens. The graceful violet-green swallow is unsurpassed in beauty of form and color, and the crested jay, magpie, and nutcracker are conspicuous for their handsome appearance and vigorous flight. Among birds particularly interesting because of curious and unusual habits are the broadtailed hummingbird, water ouzel, campbird, nuthatch, nighthawk, and the ptarmigan, pipit, and rosy finch of the high peaks.

Although widely distributed through the park, birds are more numerous along streams and near open marshes and meadows than in the dense forests. About 100 species are found regularly in summer, and nearly 150 have been recorded during the whole year.

Flowers

This park is especially notable for the presence of the blue columbine and many beautiful flowers of the gentian and primrose families; for the profusion of dwarf alpine plants on the meadows above timberline; and for the brilliance of certain species found in moist glades of the subalpine zone. Striking examples of the latter are the tall blue larkspur and monkshood, of many vivid hues, and the curious little red elephant.

Conspicuous and characteristic flowers of the lower altitudes are the mariposa lily, iris, wallflower, gaillardia, and numerous species of cinquefoil, pentstemon, and evening primrose. Among the less common groups, several delicate species of orchid, pyrola, violet, and anemone will delight the botanist. Over 700 distinct species of flowering plants have been collected within the park, and doubtless many more await discovery and identification by the careful student.

Trees

The principal trees are the Engelmann spruce, which forms extensive primeval forests in the subalpine region, the lodgepole pine, the prevailing tree of middle elevation, very common in second growth, and the ponderosa pine, a large spreading tree, occurring mainly in the lower valleys and foothills. The limber pine is frequent in high rocky places, assuming picturesque forms at timberline, and the Douglas fir, or false hemlock, is widely distributed, while the blue spruce and alpine fir are confined to moist stream banks. In addition to the coniferous trees, there are three species of poplar, of which the commonest is the well-known quaking aspen, growing in scattered groves throughout the park.

AUTOMOBILE TRIPS

Denver Circle Trip

The Trail Ridge Road, which crosses the Continental Divide in Rocky Mountain National Park, offers a grand circuit of Colorado's beauties that forms one of the most attractive and impressive of the scenic automobile trips of our country.

The trip starts from Denver, crosses the Continental Divide at Milner Pass in Rocky Mountain National Park, reaches Grand Lake, crosses the Continental Divide again at Berthoud Pass, traverses the Denver Mountain Parks, and returns to Denver, having completed without any duplication 240 miles of comfortable travel through magnificent country, full of interest and variety; the trip can be made in 2 days or it can be prolonged to suit individual time and inclination. It combines in one trip half a dozen features, any one of which by itself would be worth the journey. The Rocky Mountain Parks Transportation Co. operates daily scheduled trips over this route during the summer season.

On leaving Denver the road leads out Federal Boulevard, crosses Westminster Heights, from which point there is an extensive view of the Great Plains to the east and a panorama of the Front Range of the Rocky Mountains to the west, stretching out before the eye from Pikes Peak to Longs Peak, a rampart of mighty mountains, 125 miles from end to end. The road then passes through a farming section, where irrigation has turned what was once an arid plain into a richly productive district. Fields of deep green alfalfa alternate with the waving wheat, and in the fall of the year the harvesting and threshing add new life to the landscape. Next is the town of Lafayette, where coal mining is the principal industry, and then the road traverses a sugar-beet country. Colorado is the sugar bowl of the United States, and here is one of the regions where the beets are most successfully grown. At Longmont and Loveland
