So we see that the glacier acquires its cargo of rock not only by scraping its sides and plucking it from the bottom of its cirque and valley, but by quarrying backward till undermined material drops upon it; all of this in fulfilment of Nature's purpose of wearing down the highlands for the upbuilding of the hollows.
This is not the place for a detailed description of Mount Rainier's twenty-eight glaciers. A glance at the map will tell something of the story. Extending northeasterly from the summit will be seen the greatest unbroken glacial mass. Here are the Emmons and the Winthrop Glaciers, much the largest of all. This is the quarter farthest from the sun, upon which its rays strike at the flattest angle. The melting then is least here. But still a more potent reason for their larger mass is found in their position on the lee quarter of the peak, the prevailing winds whirling in the snow from both sides.
The greater diversification of the other sides of the mountain with extruding cliffs, cleavers, and enormous rock masses tends strongly to scenic variety and grandeur. Some of the rock cleavers which divide glaciers stand several thousand feet in height, veritable fences. Some of the cliffs would be mountains of no mean size elsewhere, and around their sides pour mighty glacial currents, cascading to the depths below where again they may meet and even merge.
The Nisqually Glacier naturally is the most celebrated, not because of scenic superiority, but because it is the neighbor and the playground of the visiting thousands. Its perfect and wonderful beauty are not in excess of many others; and it is much smaller than many. The Cowlitz Glacier near by exceeds it in size, and is one of the stateliest; it springs from a cirque below Gibraltar, a massive near-summit rock, whose well-deserved celebrity is due in some part to its nearness to the travelled summit trail. The point I am making is not in depreciation of any of the celebrated sights from the southern side, but in emphasis of the fact that a hundred other sights would be as celebrated, or more celebrated, were they as well known. The Mount Rainier National Park at this writing is replete with splendors which are yet to be discovered by the greater travelling public.
