The varied climate of this peak makes a large appeal to bird-life. Upward of one hundred species are found here. People from every part of the Union are here often startled by the presence of birds which they thought were far away at home. At the base the melodious meadowlark sings; along the streams on the middle slopes lives the contented water-ouzel. Upon the heights are the ptarmigan and the rosy finch. Often the golden eagle casts his shadow upon all these scenes. The robin is here, and also the bluebird, bluer, too, than you have ever seen him. The Western evening grosbeak, a bird with attractive plumage and pleasing manners, often winters here. The brilliant lazuli bunting, the Bullock oriole, the red-shafted flicker, and the dear and dainty goldfinch are present in summer, along with mockingbirds, wrens, tanagers, thrushes, and scores of other visitants. A few migratory species winter about the foot of the peak. In summer they fly to the upper slopes and nest and raise their young in the miniature arctic prairies of the heights. With the coming of autumn all descend by easy stages to the foot. The full distance of this vertical migration could be covered in an hour's flight. Many of the north-and-south-migrating birds travel a thousand times as far as these birds of vertical migration. The big game which formerly ranged this peak included buffalo, deer, elk, mountain sheep, the grizzly, the black bear, the mountain lion, the fox, the coyote, and the wolf. Along the descending streams, through one vertical mile of altitude, were beaver colonies, terrace upon terrace. No one knows how many varieties of wild flowers each year bloom in all the Peak's various ragged zones, but there are probably no fewer than two thousand. Along with these are a number of species of trees. Covering the lower part of the mountain are growths of cottonwood, Douglas spruce, yellow pine, white fir, silver spruce, and the Rocky Mountain birch. Among the flowering plants are the columbine, shooting-star, monkshood, yucca or Spanish bayonet, and iris. Ascending, one finds the wintergreen, a number of varieties of polemonium, the paintbrush, the Northern gentian, the Western yarrow, and the mertensia. At timber-line, at the altitude of about eleven thousand five hundred feet, are Engelmann spruce, arctic willow, mountain birch, foxtail pine, and aspen. At timber-line, too, are the columbine, the paintbrush, and a number of species of phlox. There are no trees in the zone which drapes the uppermost two thousand feet of the summit, but in this are bright flowers,--cushion pinks, the spring beauty, the alpine gentian, the mountain buckwheat, the white and yellow mountain avens, the arctic harebell, the marsh-marigold, the stonecrop, and the forget-me-not. One summer I found a few flowers on the summit.
