It is these cirques and valleys which constitute Glacier's unique feature, which make it incomparable of its kind. Glacier's innermost sanctuaries of grandeur are comfortably accessible and intimately enjoyable for more than two months each summer. The greatest places of the Canadian Rockies are never accessible comfortably; alpinists may clamber over their icy crevasses and scale their slippery heights in August, but the usual traveller will view their noblest spectacles from hotel porches or valley trails. This comparison is useful because both regions are parts of the same geological and scenic development in which Glacier may be said to be scenically, though by no means geologically, completed and the Canadian Rockies still in the making. A hundred thousand years or more from now the Canadian Rockies may have reached, except for coloring, the present scenic state of Glacier. Glacier National Park hangs down from the Canadian boundary-line in northwestern Montana, where it straddles the continental divide. Adjoining it on the north is the Waterton Lakes Park, Canada. The Blackfeet Indian Reservation borders it on the east. Its southern boundary is Marias Pass, through which the Great Northern Railway crosses the crest of the Rocky Mountains. Its western boundary is the North Fork of the Flathead River. The park contains fifteen hundred and thirty-four square miles. Communication between the east and west sides within the park is only by trail across passes over the continental divide. There are parts of America quite as distinguished as Glacier: Mount McKinley, for its enormous snowy mass and stature; Yosemite, for the quality of its valley's beauty; Mount Rainier, for its massive radiating glaciers; Crater Lake, for its color range in pearls and blues; Grand Canyon, for its stupendous painted gulf. But there is no part of America or the Americas, or of the world, to match it of its kind. In respect to the particular wondrous thing these glaciers of old left behind them when they shrank to shelved trifles, there is no other. At Glacier one sees what he never saw elsewhere and never will see again--except at Glacier. There are mountains everywhere, but no others carved into shapes quite like these; cirques in all lofty ranges, but not cirques just such as these; and because of these unique bordering highlands there are nowhere else lakes having the particular kind of charm possessed by Glacier's lakes.
