From the white sides of McKinley and his giant neighbors descend glaciers of enormous bulk and great length. Their waters drain on the east and south, through the Susitna River and its tributaries, into the Pacific; and on the north and west, through tributaries of the Yukon and Kuskokwim, into Bering Sea.

The south side of McKinley is forbidding in the extreme, but its north and west fronts pass abruptly into a plateau of gravels, sands, and silts twenty-five hundred to three thousand feet in altitude, whose gentle valleys lead the traveller up to the very sides of the granite monster, and whose mosses and grasses pasture the caribou.

The national park boundaries enclose immense areas of this plateau. The contours of its rounded rolling elevations mark the courses of innumerable streams, and occasionally abut upon great sweeping glaciers. Low as it is, the plateau is generally above timber-line. The day will come when roads will wind through its valleys, and hotels and camps will nestle in its sheltered hollows; while the great herds of caribou, more than one of which has been estimated at fifteen hundred animals, will pasture like sheep within close range of the camera. For the wild animals of McKinley National Park, having never been hunted, were fearless of the explorers, and now will never learn to fear man. The same is true in lesser measure of the more timid mountain sheep which frequent the foothills in numbers not known elsewhere. Charles Sheldon counted more than five hundred in one ordinary day's foot journey through the valleys.

The magic of summer life on this sunlit plateau, with its limitless distances, its rushing streams, its enormous crawling glaciers, its waving grasses, its sweeping gentle valleys, its myriad friendly animals, and, back of all and commanding all, its never-forgotten and ever-controlling presence, the shining Range and Master Mountain, powerfully grip imagination and memory. One never can look long away from the mountain, whose delicate rose tint differentiates it from other great mountains. Here is ever present an intimate sense of the infinite, which is reminiscent of that pang which sometimes one may get by gazing long into the starry zenith. From many points of view McKinley looks its giant size. As the climber ascends the basal ridges there are places where its height and bulk appall.

Along the northern edge of the park lies the Kantishna mining district. In 1906 there was a wild stampede to this region. Diamond City, Bearpaw City, Glacier City, McKinley City, Roosevelt, and other rude mining settlements came into rapid existence. Results did not adequately reward the thousands who flocked to the new field, and the "cities" were abandoned. A hundred or two miners remain, scattered thinly over a large area, which is forested here and there with scrubby growths, and, in localities, is remarkably productive of cultivated fruits and vegetables.

Few know and few will know Mount McKinley. It is too monstrous for any but the hardiest to discover its ice-protected secrets. The South Peak, which is the summit, has been climbed twice, once by the Parker-Browne party in 1912, after two previous unsuccessful expeditions, and once, the year following, by the party of Archdeacon Hudson Stuck, who gratified an ambition which had arisen out of his many years of strenuous missionary work among the Alaskan Indians. From the records of these two parties we gather nearly all that is known of the mountain. The North Peak, which is several hundred feet lower, was climbed by Anderson and Taylor of the Tom Lloyd party, in 1913.

From each of these peaks an enormous buttressing ridge sweeps northward until it merges into the foothills and the great plain. These ridges are roughly parallel, and carry between them the Denali Glacier, to adopt Belmore Browne's suggested name, and its forks and tributaries. Up this glacier is the difficult passage to the summit. Tremendous as it is, the greatest perhaps of the north side, the Denali Glacier by no means compares with the giants which flow from the southern front.

In 1903 Judge James Wickersham, afterward Delegate to Congress from Alaska, made the first attempt to climb McKinley; it failed through his underestimation of the extensive equipment necessary. In 1906 Doctor Frederick A. Cook, who meantime also had made an unsuccessful attempt from the north side, led an expedition from the south which included Professor Herschel Parker of Columbia University, and Mr. Belmore Browne, artist, explorer, and big game hunter. Ascending the Yentna River, it reached a point upon the Tokositna Glacier beyond which progress was impossible, and returned to Cook Inlet and disbanded. Parker returned to New York, and Cook proposed that Browne should lay in a needed supply of game while he, with a packer named Barrill, should make what he described as a rapid reconnaissance preparatory to a further attempt upon the summit the following year. Browne wanted to accompany him, but was overpersuaded. Cook and Barrill then ascended the Susitna, struck into the country due south of McKinley, and returned to Tyonik with the announcement that they had reached the summit. Cook exhibited a photograph of Barrill standing upon a crag, which he said was the summit. A long and painful controversy followed upon Cook's return east with this claim.

In all probability the object of the Parker-Browne expedition of 1910 was as much to follow Cook's course and check his claim as to reach the summit. The first object was attained, and Herman L. Tucker, a national forester, was photographed standing on the identical crag upon which Cook had photographed Barrill four years before. This crag was found miles south of McKinley, with other peaks higher than its own intervening. From here the party advanced up a glacier of enormous size to the very foot of the upper reaches of the mountain's south side, but was stopped by gigantic snow walls, which defeated every attempt to cross. "At the slightest touch of the sun," writes Browne, "the great cliffs literally smoke with avalanches."

The Parker-Browne expedition undertaken in 1912 for purposes of exploration, also approached from the south, but, following the Susitna River farther up, crossed the Alaska Range with dog trains to the north side at a hitherto unexplored point. Just before crossing the divide it entered what five years later became the Mount McKinley National Park, and, against an April blizzard, descended into a land of many gorgeous glaciers. "We were now," writes Belmore Browne, "in a wilderness paradise. The mountains had a wild, picturesque look, due to their bare rock summits, and big game was abundant. We were wild with enthusiasm over the beauty of it all, and every few minutes as we jogged along some one would gaze fondly at the surrounding mountains and ejaculate: 'This is sure a white man's country.'"
